Re: ICE in optimized build of 20000103

Hi Alexandre,

I applied your patch to the 20000104 snapshot, reconfigured with
CFLAGS set to:

-O3 -march=pentiumpro -ffast-math -funroll-loops -fomit-frame-pointer
 -malign-double -fforce-mem -fforce-addr

reconfigured, and did a bootstrap build (in a clean directory).  I get
past the old problem, but now die in the stage2 build of libiberty

This didn't happen with the default build parameters (before I applied your
patch).
