/usr/bin/xgettext: warning: The option --msgid-bugs-address was not specified.
                            If you are using a `Makevars' file, please specify
                            the MSGID_BUGS_ADDRESS variable there;
otherwise please
                            specify an --msgid-bugs-address command line
option.

po/ChangeLog:
2006-05-06  Eric Blake  <address@hidden>

        * Makevars (MSGID_BUGS_ADDRESS): Add.
        * POTFILES.in (src/getopt.c, src/version-etc.c): These files live
        in src, not gnu.
