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.
The -path flags in the RGL modules compiled during 'cabal build' now refer
directly to the needed source directories. References 'alltenses' and 'present'
(and the nonexistent directory 'mathematical') have been removed.
This allows the files to be compiled in any order (e.g. in parallel). In
addition, you can do things like
gf -retain lib/src/api/TrySwe.gf
without compiling/installing any other RGL modules first, and without
setting any other path flags or environment variables.
