Re: Fwd: "getopt.h" no longer part of <stdlib.h>

getopt.h never was included in stdlib.h.  Old SysV systems included it
in stdio.h which was deprecarted in Unix98 and will be removed in the
next revision.

The only portable way to get to the prototypes is using unistd.h.
Which is of course logical since getopt is a POSIX function.
