>(137)  warning: main() returns random value to invocation environment

     Syntactically, "exit(0)" is a function call.  How the heck do you
expect lint to know that exit() never returns?  Since main() is
usually declared to be of type int, then lint is fully justified in
expecting to see a "return <something>" at the end of main().  You
will have to either live with the lint warning, or cause main() to
return something.

     How about:

	return(exit(0));
}

     That should keep lint happy!
