Actually, 0 or EXIT_SUCCESS.

1 is not well-defined under MVS.  Normally, 0 is success, 4 is
warning, 8 is error, 12 is severe error, 16 is catastrophic error.

I think EXIT_FAILURE is generally set to 8.

I think VMS has some scheme where even numbers are
errors, odd numbers are OK, so although I don't recall
seeing it implemented that way, I would expect to see
0 get translated into 1 on the way out.

The C standard is written that way because it was the best
compromise available.

I think the current C code is fine, ie it conforms to C89.
But if a non-default option called:


was to be defined, that passed err unchanged to exit, that would
be fine by me too.
