You could try MSTA from COCOM toolset. You can find it on

MSTA implements POSIX YACC + many extensions.

MSTA supports LALR(k)- and LR(k)-grammars (k>0). Moreover it generates
only code which makes minimal lookahead for resolving each conflict.

It works on the most of Unixes and WIN32. There is installshield
version of distribution and also sources which can be compiled by
Microsoft VC++ version 6.0 or CYGWIN.

It generates C and C++ code.

It supports this for WIN32.

There is standard YACC error recovery and improved one.

You can use YACC %prec constructions and special constructions which
constrain lookahead when you generate a LALR(k) or LR(k) parser for k >

It can output all LR-situations of LR-set and LR-situations with context
for better debugging.
