[gdal-dev] compiling GDAL with GEOS on Windows

[Yilmaz Arslanoglu]

Hi Bhasker;

I use Visual Studio 2008, but actually the problem was
forgetting to make a complete clean before building it with
the modified options. So as Frank said, it will be nice
to call "nmake /f makefile.vc clean" before the build.

Regards,
Yilmaz
