Backtracking parser generator based on byacc

btyacc is a hacked version of the original Berkeley "byacc". The main change to byacc is the addition of backtracking code, allowing you to try both alternatives in case of shift-reduce or reduce-reduce conflicts. As long as no backtracking takes place, speed is comparable to bison.

Additional features: - enhanced support for storing of text position information for tokens - closes the potential *yacc/bison memory leak during error recovery - preprocessor directives like %ifdef, %include - C++ friendly
