Ok, the windows includes are out it seems.

But guile seems to export functions that use types defined in gmp.h (mpz_ 
stuff).

Guile linux has the same dependency and on linux the gmp.h header file is 
available. But only because guile requires it.

I'm a bit unsure how to tackle this one. If gmp is required for guile (a 
required dependency for gnucash), shouldn't gnucash then also require gmp 
explicitly, meaning some extra code should be added to configure.ac ? Or 
should I just add the proper paths for the gmp library and header files in the 
gnucash configure line in the Windows' intall script ?
