[Scummvm-cvs-logs] CVS: scummvm/scumm imuse.cpp,2.117,2.118

[Jerome Fisher]

Update of /cvsroot/scummvm/scummvm/scumm
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv24774

Modified Files:
	imuse.cpp 
Log Message:
The Adlib MidiDriver is now initialised immediately when it is determined that it may be used. Doing this lazily potentially deadlocked when using MT-32 emulation in mixed MIDI/Adlib mode.
