Hello,
I am testing gcc-3.4-20031210. Bootstrapping fails with
this problems:

When I compile libgcc with the same flags with a crosscompiler this
doesnt happen so it appears the compiler has miscompiled itself
somewhere else.. anyone else seen this?
I tried bootstrapping from gcc2723 and a 386 hosted gcc-3.2 crosscompiler,
same result both times.
The crosscompiler so far works pretty well btw, working 2.4 & 2.6
kernels and some 3.2 problems fixed.
