While the abstract Numeral inherits only Cat[Numeral,Digits], some of the concrete NumeralNNN of Numeral inherited everything from CatNNN. Normally the compiler outputs a warning message when a concrete syntax contains superflous lincats, but apparently not when they get included through inheritance... This does not seem to cause problems in the Haskell run-time system, but the C run-time system fails to load PGFs with superflous lincats. This problems shows up when creating application grammars that inherit Numeral. The Phrasebook is an example of such a grammar.
