GMP on PowerPC 970

[Brendan Younger]

I've been trying to compile GMP with "longlong" limb support for my 
PowerPC 970 running Mac OS X.  After hacking the configure script to 
recognize my machine and using the generic powerpc64 umul_ppmm, it 
compiles nicely (although there are a few warnings related to comparing 
32-bit and 64-bit integers) but fails a few tests in MPZ, namely t-mul, 
t-div, t-bin, etc.  Has anyone succeeded in compiling this with 64-bit 
limb support, or should I just sit around and wait for Mac OS X to 
become 64-bit?
