Hi Marion,

It's actually very straightforward to compile GEOS on windows.  Since
you're already familiar with commandline through your GDAL build, here
are my steps (note that others likely use cmake or other methods, but
this is what works for me).

- download 3.3.8 from http://trac.osgeo.org/geos/
- in MSVC command window:
  - cd to geos-3.3.8
  - autogen.bat
  - nmake /f makefile.vc MSVC_VER=1500
- output is in /src/
- cd into gdal
- edit nmake.opt
  - change GEOS_DIR, GEOS_CFLAGS, GEOS_LIB variables for your local paths
- nmake /f makefile.vc clean
- nmake /f makefile.vc

(this is what I've been doing for MS4W for many years)

Enjoy,

-jeff
