>Description:
Building gcc-2.95.3 fails after stage1/xgcc has been build. Make aborts with:

stage1/xgcc -Bstage1 -B/MCM/gnu/m88k-motorola-sysv4/bin/ -DIN_GCC -DNO_BUGS -D__STDC__=0 -O -DHAVE_CONFIG_H -o genrecog genrecog.o rtl.o bitmap.o print-rtl.o ... (with obstack.o and alloca.a as it seems)
./genrecog ../../gcc-2.95.3/gcc/config/m88k/m88k.md > tmp-recog.c
genrecog: Internal compiler error in `merge_trees' at .../gcc/genrecog.c:968
Pleas submit a full bug report (hope that's full enough).

The genrecog previous to that did not fail. I will try with other options some other time.
>How-To-Repeat:
mkdir objdir; cd objdir
../gcc-2.95.3/configure --prefix=/MCM/gnu --enable-lanuages=c
gmake CFLAGS="-O" LIBCFLAGS="-O" BOOT_CFLAGS="-O2" bootstrap
