Have you ever written a program like this:

main ( int argc, char *argv[] ) 
{
	/* do something with argv, but not argc */
}

and the warning:
"prog.c": line 4: warning: argc not used

The solution:

main ( int, char *argv[] )
{
	/* do something with argv, but not argc */
}

Obvious really, but not to many C programmers.
