It seems that compat/poll/poll.c also defines _WIN32_WINNT (but only
with _MSC_VER defined).  The change to git-compat-util.h in this
patch avoids redefinition for both MinGW and MSVC case.  Do you also
need to have this, too?

Here is what I tentatively queued on top of the three from Karsten,
and your "Fix stat definitions".

Subject: [PATCH] Windows: do not redefine _WIN32_WINNT

With MinGW runtime version 4.0 this interferes with the previous
definition from sdkddkver.h.
