[Proj] Building for and calling from g95-MinGW

[Jan Hartmann]

Long ago, I did this using named common blocks and extern C structs. Why 
won't you use named common blocks? I understand the dangers of the 
unnamed common, though.

Fortran 90 seems to have more possibilities for data representation. I 
never worked with it, but see an example at:
