Someone at Sun must have had a different model indeed, for alas,
in at least one major release, their startup code amounts to this:

	push argc, argv, envp
	call main
	push 0
	call exit

This means that

    main( ... ) ... return (EX_USAGE); ...

will return not exit code 64, but rather code 0 (success).
