# we need a proper glibc version for the Scrt1.o provided to the pie-ssp specs
# we also need at least glibc 2.3.3 20040420-r1 in order for gcc 3.4 not to nuke
# SSP in glibc.

# NOTE: we SHOULD be using at least binutils 2.15.90.0.1 everywhere for proper
# .eh_frame ld optimisation and symbol visibility support, but it hasnt been
# well tested in gentoo on any arch other than amd64!!

# Recently there has been a lot of stability problem in Gentoo-land.  Many
# things can be the cause to this, but I believe that it is due to gcc3
# still having issues with optimizations, or with it not filtering bad
# combinations (protecting the user maybe from himeself) yet.
#
# This can clearly be seen in large builds like glibc, where too aggressive
# CFLAGS cause the tests to fail miserbly.
#
# Quote from Nick Jones <carpaski@gentoo.org>, who in my opinion
# knows what he is talking about:
#
#   People really shouldn't force code-specific options on... It's a
#   bad idea. The -march options aren't just to look pretty. They enable
#   options that are sensible (and include sse,mmx,3dnow when apropriate).
#
# The next command strips CFLAGS and CXXFLAGS from nearly all flags.  If
# you do not like it, comment it, but do not bugreport if you run into
# problems.
