The LINK program that comes with MSC 5.1 is supposed to recognize that
switch.  Methinks you are inadvertently executing an older version of LINK.

Have you checked your search PATH for a directory that may contain such
a critter, perhaps a directory with a name like MSDOS that contains the
older version usually supplied with the DOS system?  Look also in your
current directory, where your source files are.
