I'm running Mac OS X 10.6.

How do I force configure to compile in 32 bit mode?

You could simply set the CFLAGS and CPPFLAGS :

export CFLAGS=-m32

export CPPFLAGS=-m32

These flags will simply force gcc to use the -m32 option, which compiles into 32 bits mode.

So if you only have one file to compile, you can use:

gcc -m32 myfile.c
