wine users - Dec 2010 - Deconflict Unix Forward / and Windows Back Slash \ Directory

Is it possible to tell WINE to deconflict Unix-style forward slashes and
Windows-style backslashes in directory names? I have a problem where a .EXE file
goes looking for directory and file names that look like

/home/base_dir\sub_dir\file.dat

[NOTE mixed forward slash and backslash / vs \ in full directory name]

The base directory "/home/base_dir" is passed to the .EXE (which it
finds successfully), but then the .EXE appends its own subdirectory and files
names with the incorrect backslash delimiter. Needless to say, the .EXE cannot
find the files it needs. Passing in the base directory as
"\home\base_dir" doesn't work at all because this syntax is
incorrect on BSD.

Is there some flag or trick to tell WINE to interpret the correct directory
syntax on BSD? I'm stuck with the executable I have.

What are you really trying to achieve? It sounds like you are creating some
script to start an application or some wrapper. If that's the case winepath
might be what you want.
