** DWORD HXGetWinVer( HXVERSIONINFO *pVersionInfo )
*
*  PARAMETERS:
*              pVersionInfo : A pointer to the version info struct to receive the
*                             results.  (Can be NULL, in which case our only side
*                             effect is our return value).
*
*  DESCRIPTION:
*              Gets information on the Windows platform and version we are running on.
*
*  RETURNS:
*              A flag indicating the platform we are running on.
*
*              If this is a 16bit build of a Helix module, then
*              one of the following values is possible:
*
*                      HX_PLATFORM_WINNT
*                      HX_PLATFORM_WIN95
*                      HX_PLATFORM_WIN16
*
*              If this is a 32bit build of a Helix module, then
*              one of the following values is possible:
*
*                      HX_PLATFORM_WINNT
*                      HX_PLATFORM_WIN95
*                      HX_PLATFORM_WIN32S
*
*  NOTES:
*    The behavior of the GetVersion() API is totally different under
*    16bit and 32bit builds. As such we have been forced to implement
*    this function differently for each compiler version.
