'exit(1);' considered useless (slight flame)

[Charles LaBrec]

While exit(errno) is more useful than exit(1) everywhere, I would rather
see a perror() followed by an exit with a value from <sysexits.h>.  The
trouble is that not all errors come from system calls, and who really
wants to check the exit status to determine the actual error.  Furthermore,
if I do an exit(EPERM), I'd really like to know which file I failed on.
