Yes.

No, we've been trying to establish whether the patches to build with
mingw were intended to produce such a compatible build. It's not
clear, but so far it seems that apparently that is *not* the intent
(and worse, mingw-w64 may not even be able to build viable executables
that link with msvcr100 without some heavy hacking, although that's
still somewhat unclear).
