Failure running 1998-era online manual

[Dan Kegel]

I grabbed Wine-20021125 and built it on my Red Hat 7.3 box.

Its behavior installing
http://enduser:enduser@bbs.toshiba.co.uk/file/area128/S22D95UM.ZIP
(the Windows 95 version of the user manual for my 1998-era Toshiba laptop)
seems much improved over May/June 2002 wine, cool!

However, running the app does no better.  To run the app, you do
   cd 'c/Program Files/DOC'
   wine edoc32.exe TOSHIBA.M14
On Windows, it works fine.  On Wine, it displays a splash screen, then exits.

Here's a partial log:

err:mmio:MMIO_ParseExtA + but no . in szFileName: "+init"

It sounds like mmioOpen's documentation at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/mmfunc_665q.asp
is incomplete; it doesn't describe what the function does when
there's no filename, just a +init, in the string passed to mmioOpen.
I tried patching the source for MMIO_ParseExtA to assume an extension of ""
in this case, but it didn't help, the program still exits.

Any suggestions?
