Mmmh, no, the ## construct has been in gcc forever

My understanding is that in macros, you are supposed to use ## between a
macro name and something you'd want to be next to it.

That said, #VAR ## ": " ## TYPE  makes sense, but indeed,  & ## VAR isn't
needed, I'll remove that one for now.

However, the other ones are really supposed to be there AFAIK.
Unless someone on top of C standards tells me otherwise, I'm enclined to
leave them.
I'll ask around

I also think something is fishy with your gcc, it should *really* accept
that syntax.

I can't bring myself down to that, it's just too ...stupid...
Man, I hate C :-)
