Drive C: is not necessarily the truly central drive. I have seen Windows installs that installed on D: and have C: as a permanently mounted network share. To assume that drive C: is always what it is... is blasphemy. However, Wine does make this assumption, and probably the patch would be appropriate. Just throwing that out there. However, I have also seen wine installs onto a network where the WINEPREFIX is a network share so that multiple people can use the same program.

This patch should fix 17619 for new wineprefixes and other cases where C: is
created. The logic is that C: should never be registered as a network share,
which is the issue in 17619. It was suggested as a response to a previous patch
that this should be relative to %SYSTEM% or something along those lines, but I
believe that C: is a true special case, similar to how A: and B: are always
reserved for floppy drives.

I'm not sure if this is the right way to go, so I'd like comments :) Thanks
