yacc - Yet Another Compiler Compiler

a unix (first appeared there) based parser generator.
Incarnations are bison (gnu based) and byacc (Berkeley yacc).

You give it a syntax file (grammar) with the extension
.y and it produces a parser. You also need to supply a 
tokenizer or 'lexer'. This is supplied by lex.

All this is available as ports to djgpp.
