By looking at argv[0], of course:

	extern int __crt0_argc;
	extern char **__crt0_argv;

These are global variables defined in the startup code which hold the
values of `argc' and `argv' passed to your `main' function.

Note that this is *very* DJGPP-specific (I'm not sure it won't break
even in DJGPP v1.x).
