The warnings can be an important clue on what is wrong, especially if there are 
warnings when compiling fluid_winmidi.c and fluid_dsound.c

Something is wrong with midiInOpen() parameters [1], in fluid_winmidi.c line 
172 or around. Lines 77 and 275 should also match the prototype of MidiInProc() 
[2]. Try changing (DWORD) by (DWORD_PTR).

I don't have a 64 bit windows machine to test, sorry.

Pedro
