A quick test to build wxPython with a freshly compiled python-mingw with
binascii package results in the next problem. One that looks a bit more
fundamental to sort out:

This is what I get compiling the most basic of extension with this
python-mingw, the error is the same when trying to build wxPython too:

Basically it's down to not having pywin32 installed or any other win32api
module. The trouble is they all seem to require compiling with msvc.

I've run out of time again.

Best Regards, Brian.
