gnupg/keyserver/gpgkeys_hkp.c
David Shaw 0a86b45b9d * gpgkeys_hkp.c, gpgkeys_ldap.c: #include <getopt.h> if it is available. 
Also include extern references for optarg and optind since there is no
guarantee that any header file will include them.  Standards?  We don't
need no stinkin' standards

* Makefile.am: Use @GETOPT@ to pull in libiberty on those platforms that
need it.
