+Subject: [PATCH 5/6] utils/pmx/pmx-src/libf2c/f2c.h: remove unnecesary macro
+ for abs()
+
+On POSIX systems, abs() is a function provided by your C Standard library,
+so we don't need to define it as a macro.  It is dangerous to do so because
+if f2c.h is included before stdlib.h, then then macro breaks the function
+prototype.
+
