C preprocessor macro expanding itself

I believe that the answer to my question is tied to C Preprocessor, Stringify the result of a macro. However, I'm having trouble applying the solution to my use case.

I have this function:

astNodePtr createNode(int lineno, int nodeType, ...);

I have this macro which goes along with it:

#define NODE(nodeType, ...) createNode(yylineno,nodeType,##__VA_ARGS__)

All works fine until I get to a line like this:

NODE(1,x,NODE(2,y,z))

My linker gives me an error: undefined reference to 'NODE'

EDIT:

I've tried (inspired by the fore-mentioned link)

#define EXPAND(x) ##x#define NODE(nodeType, ...) createNode(yylineno,nodeType, EXPAND(__VA_ARGS__))

However, I got the same error.

EDIT:

I should mention that I also use the macro thus: NODE(5)

Therefore, I need the ## in front of __VA_ARGS__ in order to avoid the trailing comma problem.
