That is ancient history and does not conform to the ANSI/ISO C standard
which requires that 0 be interpreted as a successful exit status.  The
VMS C run-time library was fixed long ago to do so, so no changes are
necessary.  According to ANSI/ISO C, the only portable exit statuses are
0 or EXIT_SUCCESS (which are interpreted as success), and EXIT_FAILURE
(which is interpreted as failure).  Trying to return different flavors
of success or failure, particularly using hard-coded values like 1 and
2, is non-portable and doomed to failure.
