Error building gas from binutils-2.13.1

[Thomas Koeller]

When building binutils-2.13.1 from sources, I get a couple of warnings
that look very suspicious to me. I am building a cross assembler for a
powerpc-eabi target on a i686-pc-linux-gnu host. Compilation of
gas/config/tc-ppc.c produces the following output:

I already reported the ICE to the gcc bug tracking system (optimization/8557). 
It seems to me, however,
that the warnings generated indicate a severe problem with this source module's 
logic.
