An easier way, or if they haven't a C compiler, is to use Perl. I think
Solaris 8 has 5.004 installed.
$ perl -le 'exec("./startloopstop") or print "failed: $! ", $! + 0'
failed: Permission denied 13
$
$! is perl's `errno' value, we print it as a string first, and then as
an integer.
Cheers,
Ralph.
