As Robin already said, this had been fixed some time ago, but it
somehow made it back in my version.
I have to admit that the patch I sent last night was not the latest
one Robin and I had agreed on. It was the newest one I had on
my harddrive though...

Attached is another msvccompiler.py (zipped),
and hopefully Robin can agree on this one.
I've already included the doc-strings Robin has
supplied.

BTW: What is the preferred format posting sourcecode to the list?
AFAIK, zipped attachments are not so nice in the archive,
unpacked source-code has the white-space problem in
Outlook Express, which I'm using here...

As soon as you extend the distutils framework to use
temp-directories for building, I will submit a patch for msvc
again.
