 */

/* 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
