Hi,
Trunk bootstrap on powerpc64-linux (debian etch) fails on a warning
during libgomp build:

Note: this was reported on another platform as
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32193
libgomp/configure.ac has:
# Add -Wall -Werror if we are using GCC.
if test "x$GCC" = "xyes"; then
XCFLAGS="$XCFLAGS -Wall -Werror"
fi
I had to remove this part to be able to bootstrap. Now may be it's a bug
in debian etch libc headers but it would be nice to honor
--disable-werror in libgomp.
Thanks in advance,
Laurent
