[on tom's question]
IIRC, the reason you can't query Python in the same way that configure/python.m4 does is because the generated Makefile
thatsupports distutils.sysconfig does not exist in standard win32 builds. That is, AFAIK, there is no way to request
theexact path of the dll/lib file in win32. However, I'm not particularly familiar with Python on win32, so that may
notbe the case. 


Given the absence of a more precise method, I'd recommend considering something along the lines of:

Allow the user specify (config.pl?) the Python executable to build against and default to the python.exe in %PATH%.
(thismay already be the case, idk) 

Query Python for the version information and installation prefix.
python -c 'import sys; print(str(sys.version_info[0]) + str(sys.version_info[1]))'python -c 'import sys;
print(sys.prefix)'

Assume that the prefix has a normal layout, and construct the lib path from the extracted version and prefix.
