Subject: MDMLNK - Patching MDM7xx and other files without DDT or SID

Actually, if there's a standard relocatable format, with symbol table
info, etc., that's probably a better thing to do patches on.

Also, the way programs like SCCS and RCS do changes, they leave identifier
strings in the binary, that can be searched for, and indicate version info
about the program.  No reason not to use this sort of approach, within
reason...
