FWIW automoc was re-written and called am_edit in the kde-1.1.1 version and
in the KDE CVS HEAD branch. am_edit does a much better job of figuring out
what moc files to produce.

Any of these versions could be used by copying am_edit over the top of your
automoc. (Backup your old automoc first though, JIC!).

The HEAD version is more advanced than the kde-1.1.1 version, but it should
still be compatible (although I've not tried this).
