Using Wine-1.1.42, Rhiannon: The Curse of the Four Branches installer hangs
after starting up. Both the demo and the retail version is affected.

Howto reproduce the bug:
Start the installer: the company logo is shown for a couple of seconds, then
Wine hangs. Eventually an exception is generated by Wine and winedbg starts.

Bisecting between 1.1.41 and 1.1.42 resulted the following commit:

However, I couldn't cleanly revert the patch on top of 1.1.42:

patching file dlls/winmm/winemm.h

patching file dlls/winmm/winmm.c

Despite the rejected lines, the source re-compiled cleanly, and the installer
worked again.

Wine-1.1.42 compiled from source, using CFLAGS="-gdwarf-2"
