This patches seems to cause on x86_64-linux-gnu bootstrap to fail:

../../xgcc -B../../ -c -g -O2   -g -O2   -W -Wall -gnatpg -I. -I/cvs/gcc/gcc/ada s-arit64.adb

Can you try bootstrapping with Ada and fix this, please?

I configured with (from config.status):
# /cvs/gcc/configure  --prefix=/opt/gcc/3.4-devel --disable-nls --enable-threads=posix --enable-clocale=gnu --enable-__cxa_atexit --enable-shared --enable-languages=c,c++,ada,treelang,java,f77,objc --enable-checking=misc,tree,rtl,gc,rtlflag --with-system-zlib x86_64-suse-linux-gnu --with-gcc-version-trigger=/cvs/gcc/gcc/version.c

Cheers,
Andreas
