Subject: [PATCH] The getopt() prototype and externs don't belong in stdlib.h. 
 Berkeley moved them to unistd.h to match POSIX in 1995 but we never did. The
 exception to this is getsubopt() which POSIX says should be in stdlib.h.  The
 non-standard suboptarg extern remains in the BSD-only section of stdlib.h. 
 Neither getsubopt() nor suboptarg belong in unistd.h or getopt.h.  They were
 only there to allow us to protect all the getopt() bits from being multiply
 defined.  OK guenther@
