Unrelated.

If everything is compile with the same compiler (ie. using the same
runtime library), that will make the problems disappear again.

But that's not even true for all the VC built binaries in OSGeo4W (e.g.
QGIS and Qt are build with Visual C++ 2008 Express Edition, while GDAL
and python are built with VC 7.1 - I think).

AFAICS there's no way around fixing that in GRASS for OSGeo4W.

The build system currently doesn't support VC at all.  I didn't
investigate how intensive it would be to add that to the existing
Makefile, but that might be an option, too.
