The behavior of distutils with config files is mysterious, I gave up
trying to understand it long ago :) I use scripts instead to control
everything from command line.

All those refer to recently added functions, which suggest some old
files/configuration are used. Be sure to clean the working tree and
the build directory and try again.

I have just tested it on both wine and a xp vm with mingw, and both
build correctly.
