[antlr-interest] C++ doesn't like my tokens ...

[Anthony Youngman]

Hi Ric,

Not sure how to deal with this ... I've got the following tokens in my
lexer:

tokens {
// statements
	CALL="CALL";
	CALLING="CALLING";
	DEFFUN="DEFFUN";
	ELSE="ELSE";
	END="END";
	EXIT="EXIT";
	FUNCTION="FUNCTION";
	GOTO="GOTO";
	IF="IF";
	INPUT="INPUT";
	LOOP="LOOP";
	NULL="NULL";
	PRINT="PRINT";
	PROGRAM="PROGRAM";
	REPEAT="REPEAT";
	RETURN="RETURN";
	SUBROUTINE="SUBROUTINE";
	THEN="THEN";
	UNTIL="UNTIL";
	WHILE="WHILE";
// operators
	LOGIC_EQ="EQ";
// descriptors
	COMMENT;
	LABEL;
	MATFUNC;
// functions
}

Which gives me a TokenTypes.hpp as attached. Note the line "NULL = 15,"
- this causes g++ to blow up pretty badly.

Obviously my keyword is being treated as a C++ keyword. I would guess,
as a temporary measure I can manually mangle the keyword, but are there
any other keywords that are likely to blow up? And if so, how do we
handle it? Should Antlr do a little mangling of all keywords for
safety's sake?

Cheers,
Wol
