Both bison and flex will work with g++.

If you want to use ostreams (cerr) for error messages you might want
to redefine ECHO and YY_FATAL_ERROR for flex:

#include <stream.h>
#undef ECHO
#define ECHO cerr << yytext
#undef YY_FATAL_ERROR
#define YY_FATAL_ERROR(msg) { cerr << msg << '\n'; exit (1);}
#define input yyinput

I've offered some example code using bison, flex and libg++ to Doug
Lea, but haven't finished all the paperwork.  I'll post a note when
it's ready.
