I did not exactly know this - thanks for the info (I knew about
something called Visual Studio Express 2003- but that only
works/worked for Python 2.5, I think...)
Rephrasing my original question: Is the mingw-w64 at all "easy" by now
? How about cross compiling to 64bit Windows from a 32bit Ubuntu (that
I could easily run on virtualbox) ?
(But I'm not apposed at all to the "free" Windows 7 Platform SDK, so
I'll look into that -- giant download !?)
