Is it possible to compile a 32 bit version of gmp?

[Paul van Hoven]

I downloaded gmp 4.3.2 to use it on my OS X 10.6 during the gcc 
compilation process. I need gmp to compile in 32 bit but the configure 
script automatically builds a 64 bit version which leads to a 
compilation error when compiling the gcc since it needs a 32 bit 
version. Therefore I would like to know what I have to change in order 
to get a 64 bit version?
