# "make" will update the $(DOMAIN).pot and the $(CATALOGS), but subsequent
# invocations of "make" will do nothing. This timestamp would not be necessary
# if updating the $(CATALOGS) would always touch them; however, the rule for
# $(POFILES) has been designed to not touch files that don't need to be
