UnixFilenames
We need a way for applications to instruct Wine that they can deal with Unix filenames. Probably we need to have a mechanism of setting "personality" bits, similar to the kernel one.
This is important for Winelib apps that may not want to have anything to do with drives, which are a foreign concept to Unix users.
A personality bit won't work because Wine needs to use Windows file names internally for things like accessing the URL cache and other stuff under c:\windows. That means that an application that can use UNIX file names needs to call a different set of routines. There is an implementation of this available approach to this which involves automatically generating most of the UNIX file name versions of standard entry points.
