-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif

-
-   The allocation functions (scratch_buffer_grow,
-   scratch_buffer_grow_preserve, scratch_buffer_set_array_size) make
-   sure that the heap allocation, if any, is freed, so that the code
-   above does not have a memory leak.  The buffer still remains in a
-   state that can be deallocated using scratch_buffer_free, so a loop
-   like this is valid as well:

-     struct scratch_buffer tmpbuf;

-
-   scratch_buffer_grow and scratch_buffer_grow_preserve are guaranteed
-   to grow the buffer by at least 512 bytes.  This means that when
-   using the scratch buffer as a backing store for a non-character
-   array whose element size, in bytes, is 512 or smaller, the scratch
-   buffer only has to grow once to make room for at least one more

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ
-     # define environ (*rpl_environ ())

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ

-/* Set up the following warnings, based on which modules are in use.
-   GNU Coding Standards discourage the use of fseek, since it imposes
-   an arbitrary limitation on some 32-bit hosts.  Remember that the
-   fseek module depends on the fseeko module, so we only have three
-   cases to consider:
-
-   1. The developer is not using either module.  Issue a warning under
-   GNULIB_POSIXCHECK for both functions, to remind them that both
-   functions have bugs on some systems.  _GL_NO_LARGE_FILES has no
-   impact on this warning.
-
-   2. The developer is using both modules.  They may be unaware of the
-   arbitrary limitations of fseek, so issue a warning under
-   GNULIB_POSIXCHECK.  On the other hand, they may be using both
-   modules intentionally, so the developer can define
-   _GL_NO_LARGE_FILES in the compilation units where the use of fseek
-   is safe, to silence the warning.
-
-   3. The developer is using the fseeko module, but not fseek.  Gnulib
-   guarantees that fseek will still work around platform bugs in that
-   case, but we presume that the developer is aware of the pitfalls of
-   fseek and was trying to avoid it, so issue a warning even when
-   GNULIB_POSIXCHECK is undefined.  Again, _GL_NO_LARGE_FILES can be
-   defined to silence the warning in particular compilation units.
-   In C++ compilations with GNULIB_NAMESPACE, in order to avoid that
-   fseek gets defined as a macro, it is recommended that the developer
-   uses the fseek module, even if he is not calling the fseek function.
-
-   Most gnulib clients that perform stream operations should fall into
-   category 3.  */

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ
-     # define environ (*rpl_environ ())

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ
-     # define environ (*rpl_environ ())

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ
-     # define environ (*rpl_environ ())

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ
-     # define environ (*rpl_environ ())

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ
-     # define environ (*rpl_environ ())

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ
-     # define environ (*rpl_environ ())

-/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
-   for FUNCTION which will then trigger a compiler warning containing
-   the text of "literal string" anywhere that function is called, if
-   supported by the compiler.  If the compiler does not support this
-   feature, the macro expands to an unused extern declaration.
-
-   _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
-   attribute used in _GL_WARN_ON_USE.  If the compiler does not support
-   this feature, it expands to empty.
-
-   These macros are useful for marking a function as a potential
-   portability trap, with the intent that "literal string" include
-   instructions on the replacement function that should be used
-   instead.
-   _GL_WARN_ON_USE is for functions with 'extern' linkage.
-   _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
-   linkage.
-
-   However, one of the reasons that a function is a portability trap is
-   if it has the wrong signature.  Declaring FUNCTION with a different
-   signature in C is a compilation error, so this macro must use the
-   same type as any existing declaration so that programs that avoid
-   the problematic FUNCTION do not fail to compile merely because they
-   included a header that poisoned the function.  But this implies that
-   _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
-   have a declaration.  Use of this macro implies that there must not
-   be any other macro hiding the declaration of FUNCTION; but
-   undefining FUNCTION first is part of the poisoning process anyway
-   (although for symbols that are provided only via a macro, the result
-   is a compilation error rather than a warning containing
-   "literal string").  Also note that in C++, it is only safe to use if
-   FUNCTION has no overloads.
-
-   For an example, it is possible to poison 'getline' by:
-   - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
-     [getline]) in configure.ac, which potentially defines
-     HAVE_RAW_DECL_GETLINE
-   - adding this code to a header that wraps the system <stdio.h>:
-     #undef getline
-     #if HAVE_RAW_DECL_GETLINE
-     _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
-       "not universally present; use the gnulib module getline");
-     #endif
-
-   It is not possible to directly poison global variables.  But it is
-   possible to write a wrapper accessor function, and poison that
-   (less common usage, like &environ, will cause a compilation error
-   rather than issue the nice warning, but the end result of informing
-   the developer about their portability problem is still achieved):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     rpl_environ (void) { return &environ; }
-     _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
-     # undef environ
-     # define environ (*rpl_environ ())
-     #endif
-   or better (avoiding contradictory use of 'static' and 'extern'):
-     #if HAVE_RAW_DECL_ENVIRON
-     static char ***
-     _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
-     rpl_environ (void) { return &environ; }
-     # undef environ
-     # define environ (*rpl_environ ())
