Hi Jürgen,

the current development version (4.5.0) supports the following
Makefiles specifically intended for MSVC:
- makefile.vc
- makefile64.vc
- makefile_mod.vc
- makefile_mod64.vc

the first two will create the standard libspatialite, and
the second two will create mod_spatialite (the *64.vc
makefiles are intended for the 64 bit compiler).

you can download such MSVC makefiles directly from the
Fossil repository:

https://www.gaia-gis.it/fossil/libspatialite/dir?ci=tip

adapting the MSVC makefiles to previous versions shouldn't
be too much difficult (you'll probably have to just remove
few C sources introduced by 4.5.0)

bye Sandro
