thanks, i will keep trying to compile it considering your tips but it would be nice if i could test your pypm.pyd in the meantime!

I guess it is getting late. LIBCMT.LIB is one version of the VC 6.0 C
library, so apparently isn't present in VC 7.1. I expect uuid.lib is
still be available. I am not so sure about OLDNAMES.LIB, but then you
did not mention a LNK1104 for it so I assume it is also available. So
try replacing line 34 in setup.py with the following two lines:

                 libraries = ["portmidi", "winmm", "porttime"],
                 extra_link_args = ["NODEFAULTLIB:LIBCMT"])

If it the linker complains about an invalid argument try adding a
forward slash "/" before NODEFAULTLIB.
