Abstract:

    This file declares routines to mark operations on the registry.
    During the Win9x side of processing, registry operations are
    recorded in memdb to suppress Win9x settings, or to overwrite
    NT settings.  The memdb entries are queried during the registry
    merge in GUI mode.

    Use the macros at the bottom of this file.
