//  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
