This allowed me to finish stage1, but early in stage2, I get a GNAT ICE:

stage1/xgcc -Bstage1/ -B/vol/gcc/share/sparc-sun-solaris2.8/bin/ -c -g -O2      -gnatpg -gnata -I- -I. -Iada -I/vol/gnu/src/gcc/gcc-dist/gcc/ada /vol/gnu/src/gcc/gcc-dist/gcc/ada/comperr.adb -o ada/comperr.o
+===========================GNAT BUG DETECTED==============================+

This time it's a SEGV in mark_target_live_regs, resource.c (l.980) :

      regset regs_live = BASIC_BLOCK (b)->global_live_at_start;

with b = NULL ;-(
