Hi guys,
Please find enclosed a patch on PortMIDI regarding a crash on 64bits
version of Windows.
It was previously reported here and I came across it when upgrading
to Windows 8.1
http://sourceforge.net/p/portmedia/discussion/697912/thread/c2de24fd/?limit=50
The signature of some callback was wrong casting 64bits value in
32bits especially some pointer.
The definition of callbacks are the following:

Regards,
Any news about this ?
Patch inlined
