I mirrored it at least:
http://www.boblycat.org/~karltk/gcc-3.1-branch-tmp.diff.gz

It does apply cleanly to 3.2 as well. However, I ran into the problem of
missing the symbol __fpscr_values, which I believe is supposed to go into
libgcc(_s).a

If memory serves, Kaz mentioned somewhere that the above patch still has
some issues, but whether it was with FPU mode switching or with
multithreaded apps, I cannot recall.

(I think it would be the latter, as even if we put the __fpscr_values into
libgcc.a/libgcc_s.a, we need to take care of each thread having its own
storage area for 

This was with uClibc-0.9.14, gcc-3.2, binutils-2.13 and the above patch.

AFAICT, it only affects programs for which the compiler actually emits FPU
code. 


Kind regards,
