Include option for #undef for Windows

[svengiegerich]

Within the package pytsql, we encountered an issue when using speedy-antlr-tool on Windows:
👉 conflicting (uppercase) verbs with Window specific macro's.

Luckily the fix was relatively easy, at least in our case: adding #undef(see #undef) to the auto-generated *Lexer.h.

I'm not sure i understand what the specific request or issue is.

If there is an issue with the auto-generated *Lexer.h file, that is not created by this tool. Those files are generated by ANTLR, whose issue page can be found here: https://github.com/antlr/antlr4/issues

Ah, I see; I could have guessed from the comment included in the file (but was not sure whether the tool may modify the file). Thanks for the reply, and sorry for bothering!
