Might I suggest the TWS (Translator Writing System) from MetaWare.
The error handling is better than anything you will find in YACC
based systems.  The parser generated is also efficient.  Further
information can be found in various texts on compilers, including
Barret & Couch.  It is, however, not free (or cheap :-).  You can
also write or call MetaWare for more details.
