[mod_python] Compile problems - Mod_Python 3.1.4

Frank,

I may have been a little premature with the solution I offered. The 
problem I found in setup.py is in the subversion trunk version, not in 
the mod_python 3.1.4 tarball. If you are compiling from the tarball then 
your problems may lie elsewhere. If you are using the svn repository, 
then the attached patch should fix your problems.

Changes:
Fixed regular expression problem in getconfigure_option()
Fixed indent problem in getconfigure_option()
Fixed incorrect libraries list in ModPyExtension. List was specific to 
windows.

(Nicolas - I'll email the patch to python-dev in a separate message).

Regards,
Jim
