* src/gram.c, src/gram.h (ritem_print): New.

Browse Source 
* src/gram.c (dummy): Remove, now there is actual code in gram.c.
(This useless function was defined only to work around VMS linkers
that can't handle compilation units with variables only).
* src/reduce.c (dump_grammar): Use it to trace the construction of
ritem.
