However in POSIX (and even before POSIX), a nonzero value means an
unsuccessful termination. If the application developer chose to return
a nonzero value, this is probably because he wanted such an error to
be reported.

The only way to avoid making assumptions is to follow what the
standards say (regarding all exit status values as equivalent is also
an assumption). And POSIX is clear: 0 = success, nonzero = failure.
