[Wine] Checking if Wine is being used

[flyerx_2000 at yahoo.com]

Hello,

I am adapting a Windows application to make it Wine friendly. Some of
the application's operations must be changed if it is running using
Wine instead of Windows. Is there a way of checking, from within the
application, if Wine is being used?

Right now the user selects at startup if the application is running
using Wine or just Windows but it would be nice if the process was
automatic.

thanks,
