That is probably a good idea, but gmp is somewhat inconsistent there, 
i.e. it builds a 64 bit version if the hardware supports it. Defaulting 
to 32 bit since gcc also defaults to 32 bit seems like the best solution.

Shouldn't you add "-std=c99" to CFLAGS? Solaris is "correct" about that 
since it is a C99 feature IIRC :)

Sounds like a gas issue I had seen before. The Sun Freeware tools ship 
an ancient binutils. I "fixed" it by removing the "-g" flag since the 
problem was dwarf2 debugging symbols, but I might be very wrong here.

I will play around with it in the near future and let you know how it 
goes. But I am using gcc 4.2.4 and the latest binutils on Solaris 10, so 
it might not be something that is too helpful in your case.
