Strange lint mumblings

[Dave Hammond]

Can anyone explain why the statement:

    exit(0);	/* followed immediately by main's closing brace */

causes lint to complain:

ma-main.c
==============
(137)  warning: main() returns random value to invocation environment


[yes, "exit(0)" is the statement on line 137 of the file ma-main.c]
