/**********************************************************************
* VERSION_AppWinVer
* Returns the window version in case Wine emulates a later version
* of windows then the application expects.
*
* In a number of cases when windows runs an application that was
* designed for an earlier windows version, windows reverts
* to "old" behaviour of that earlier version.
*
* An example is a disabled edit control that needs to be painted.
* Old style behaviour is to send a WM_CTLCOLOREDIT message. This was
* changed in Win95, NT4.0 by a WM_CTLCOLORSTATIC message _only_ for
* applications with an expected version 0f 4.0 or higher.
