With your patch bootstrap fails on x86-64 with:
stage1/xgcc -Bstage1/ -B/opt/gcc/3.4-devel/x86_64-suse-linux-gnu/bin/ -c   -g -O2 -DIN_GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Werror -fno-common   -DHAVE_CONFIG_H    -I. -I. -I/usr/src/aj/cvs/gcc/gcc -I/usr/src/aj/cvs/gcc/gcc/. -I/usr/src/aj/cvs/gcc/gcc/config -I/usr/src/aj/cvs/gcc/gcc/../include /usr/src/aj/cvs/gcc/gcc/loop.c -o loop.o
/usr/src/aj/cvs/gcc/gcc/loop.c: In function `strength_reduce':
/usr/src/aj/cvs/gcc/gcc/loop.c:5360: warning: comparison is always 0
make[2]: *** [loop.o] Error 1

The warning wasn't there the last time I bootstrapped - but this could
be unrelated.  But as Eric pointed out, your patch is broken on x86 at
least.  I'll try now Eric's second patch,
