In my ignorance, I wonder which library the getopt(_long) calls are
taken from - is it from the kpse library or the libc++ library?  If
the prototypes are different, are the behaviours different as well?
If so, might it be wiser to rename the functions so that the behaviour
is consistent across platforms?
