Just to share some experience, I am trying to port to Windows the
Fortran interface to shapelib and gdal (fortrangis.berlios.de) and I
succeeded with GNU compilers under mingw linking to the OSGEO4W install,
despite the difficulties of sticking to an autoconf build system; I
don't know how it would be with MS compilers. Anyway shapelib has no
dependencies so I agree that an independent solution will be suitable as
well.
