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@
Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.
OK deraadt@
getopt_long_only(). At some point this should replace the BSD
getopt(3) but we are not there yet.
While I am here add protection from the multiple getopt() definitions
due to conflicting standards.
