Sure, can't use commas here.  Everything has its limitations,
and perfection is but a mirage :)
In this case, I'd have to write   int j; int k;  instead.
I have a long term # addiction and ISTR you can put all that function stuff inside brackets in the macro call and the comma problem goes away. Well I remember using () before, I guess {} will work too :)
Anyway using the preprocessor is cheating and analogous to using loadstring(). I mean its not unreasonable to treat an entire lua file as just building a string which is then called at the end to do all the things that a "normal" lua file would do. Which gives you far more power than the C preprocessor.
