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

# Stuff to test before adding ~arch
KEYWORDS="-* ~alpha amd64 arm ~hppa ~ia64 ~mips ppc ppc64 sh ~sparc ~x86"

# we need a proper glibc version for the Scrt1.o provided to the pie-ssp specs
# 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!!
