/* Module : dtwinver.cpp Purpose: Implementation of a comprehensive function to perform OS version detection Created: PJN / DATE/2 / 11-05-1996 History: PJN / DATE2.1 / 24-02-1997 A number of updates including support for NT 3.1, single mode dos in Windows 95 and better Windows version detecion under real mode dos.
