[Pythonmac-SIG] 32-bit build of Python 3.1 on 64-bit machine running Snow Leopard?

[Mitchell L Model]

Is it possible to create 32-bit build of Python 3.1 on 64-bit machine running Snow Leopard? Using the 3.1 subversion sources I have tried a variety of configure settings, but all produce 64-bit builds. The following does create a 32-bit only build for 2.6:
	configure --enable-framework --with-universal-archs=32-bit --enable-universalsdk=/

One reason I am asking is because I am curious about how the 3.1.1 binary installer, which is 32-bit only, was created -- was it just done on a 32-bit machine? I have other reasons to ask that are related to attempts to many experiments I've performed on several different machines in 10.5 and 10.6 building 3.1 and PyQt and running 3.1 inside of IDEs.
