// Contents: Stuff needed to make properties build for Nashville and
// NT... definitions of Nt property api.
//
//
// History: 07-Aug-95 BillMo Created.
// 22-Feb-96 MikeHill Fixed the non-WINNT version of
// PROPASSERTMSG.
// 09-May-96 MikeHill Update define to allow PropSet names
// to be 255 characters (from 127).
// 31-May-96 MikeHill Add OSVersion to RtlCreatePropSet.
// 18-Jun-96 MikeHill Add OleAut32 wrappers to Unicode callouts.
// 15-Jul-96 MikeHill - Remvd Win32 SEH exception-related code.
// - WCHAR=>OLECHAR where applicable.
// - Added RtlOnMappedStreamEvent
// - Added Mac versions of PROPASSERT
// 08-Nov-96 MikeHill Fixed platform-dependent #defines
