re: glibc patch needed on ppc for gcc >= 3.1 builds
Ben,
Here is the patch again with the sysdeps/powerpc/libgcc-compat.c
from glibc-2-2-branch (which doesn't use the INTUSE macro) in it.
This is essentially what we need for ppc and a template for what
the other arches will need for building glibc with gcc >= 3.1.
Jack
