* Eric POUECH :
* 98/9 added Win32 MCI support

*/
/* TODO
* + it seems that some programs check what's installed in
* registry against the value returned by drivers. Wine is
* currently broken regarding this point.
* + check thread-safeness for MMSYSTEM and WINMM entry points
* + unicode entry points are badly supported (would require
* moving 32 bit drivers as Unicode as they are supposed to be)
* + allow joystick and timer external calls as we do for wave,
* midi, mixer and aux
