[antlr-interest] using ANTLR and MySQL in C target

[Jim Idle]

The MySql headers do a lot of strange things such as #define free - it probably means that you are trying to lump everything together and include all the headers everywhere. Try splitting this out in to a supporting translation unit and just including what you need. For instance, just pass a pointer to the token text and its length and don't including the antlr headers.
