On some systems the default C compiler will not resolve multiple global
references that happen to have the same name. On some such systems the "Mcc"
command may be used to force these to be resolved. On other systems a "cc -M"
command is required. (Note that the -M flag on other systems indicates a
memory model to use!) If you have the Gnu C compiler, you might wish to use
that instead.
