[Numpy-discussion] Compiling for free on Windows32

[william ratcliff]

Hi!  What I do is make a distutils.cfg file and put in the
$PYTHONHOME/Lib/distutils

directory (for me, c:\python25\lib\distutils)

and then it will use mingw32 for the compilation.  I've attached the one I
use.

Cheers,
William
