Please open a bug at our bugzilla (  Attaching
screenshots of the problem would help.  We discourage you from working
around Wine bugs, because if we fix the bug, we'll break your app in
the process.  Better to fix Wine.

I'm not sure what you mean by different calling conventions; gcc
supports the __stdcall convention, at least, and VC++ supports
__cdecl.  If you're using __fastcall you'll need to change it to one
of the others, I think.

As far as detecting Wine, again we prefer you don't.  Would it be any
great problem to ship a Linux version that called the Linux drivers,
and a Windows version that called the Windows drivers?

It's certainly possible to open a Unix socket from a winelib app.
(Wine itself does so.)  Using a named pipe from a regular (not
winelib) Linux app won't work.

Hope that helps,
