           Summary: Option to not inherit the UNIX environment
           Product: Wine
           Version: 1.1.37
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: dima at gmail.com


The Perforce command-line client (p4.exe) breaks because of a few environment
variables that Wine inherits from the OS:

PWD: Doesn't even exist in Windows, and yet, p4 reads it and gets confused
because it's a UNIX path, not a win32 one.
P4EDITOR: I have it set to "nano", which makes sense for the Linux p4, but not
the Windows one.
P4DIFF: same as above.

p4 breaks the same way in WinXP if I set PWD to a UNIX-like path.

Since just about any UNIX environment variable can potentially break a Windows
program, it would be nice to have an option to start programs with just the
Windows environment.
(While it's possible to run "env -i wine ...", that has some disadvantages:
variables such as HOME, PATH, and DISPLAY need to be set, since they're
required by Wine; if Wine starts a native program, that program won't get the
original UNIX environment.)

Similarly, if Wine starts a native program, that program shouldn't inherit the
Windows environment.
