Optimized bootstrap failure in gcc-ss-20001023

[David Ronis]

An optimized boostrap failure on an i686-linux(2.2.17)-gnu(2.1.3)
failed in the compare stage.  A bootstrap with the default
optimization options works fine, although I get a few more testsuite
failures than I got on the last (buildable) snapshot.  

I configured and built with

CFLAGS=-O3 -march=i686 -funroll-loops -ffast-math -fomit-frame-pointer
   -fforce-mem -fforce-addr -malign-jumps=3 -malign-functions=3
   -malign-loops=3 -mpreferred-stack-boundary=3

(CFLAGS set before configuring)

Configured with: --host=i686-pc-linux-gnu --prefix=/usr --with-gnu-as
   --enable-shared --with-gnu-ld


Optimized builds haven't worked for me for quite some time.  I'm
always using the same flags given above, and always failing in the
compare stage.  However, it's usually only been in the file
java/parse.o.
