That makes it the right choice when choosing between available
compilers. For a source distribution it's also reasonable to assume
that the compiler used to build the interpreter is available which
makes it a good default. For a binary distribution assuming that the
build compiler is available is - guessing.
The MSVC version is designed to be a binary distribution. That shows
through MSVC compiler options being hardwired into distutils, unlike
the unix variation, where as far as I can see options are remembered
from the build.

I call it a default borne out of an assumption. Same difference :-)
Not a big deal, distutils is great and a good guesser;-). It just
struck me that the OPs problems were caused by distutils failing to
observe one of Tim's theses. Perhaps you feel that in this specific
case a little guesswork is warranted, if so fine with me, but it would
have been a perfectly fine alternative for distutils to print an
informative message instead.
