I could reproduce this problem.  A rebaseall broke gcc-4.  Reinstalling 
the gmp DLLs fixed it.  I didn't have any problem with the mpfr DLLs.

I have rebuilt gmp with CVS binutils and -shared-libgcc.  This fixes the 
problem for me.  Could someone (Yaakov?) download the new DLLs in 
libgmp3-4.3.1-1.tar.bz2 and libgmpxx4-4.3.1-2.tar.bz2 (below) and 
confirm the fix.
