DESCRIPTION="The GNU Compiler Collection.  Includes C/C++, java compilers, pie+ssp extensions, Haj Ten Brugge runtime bounds checking"

KEYWORDS="-* amd64 ~mips ~ppc64 ~x86 -hppa ~ppc ~sparc"

# 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!!
