Just for the record, mixing code gfortran and MSVC is a tough beast
and up to now I didn't succeed. Doing the same with g77 was easier
as MSVC could link in g77-compiled objects by also linking to libf2c
(compiled with MSVC). This provided the needed runtime functions
required by g77-compiled code.

Given all these problems, I decided to give MinGW a try, using the
latest version based on gcc-4.3.0. But recompiling all deps takes
time, given the only 30min of free time I have in the evening...
