There is no portable way to do this.

Even if there was such a way, most main() programs are written to 
completely parse their arguments and to reject any that they don't
understand.  If you were hoping to sneak in extra arguments that
your routine could parse later, you are probably out of luck.

The solution is to get the source for main() and modify it, or do something
that doesn't involve the arguments, e.g. pass the information you are
looking for in the environment, in a file, etc.  You never did get around
to explaining what it is you *really* want to do, or why you are modifying
subroutines' sources but don't have source to main().
