Please, don't depend on this, it does not exist.

Where does this come from?

Beware of common variable names such as i.

I've heard some CPP will choke on #error, even in

In Autoconf `Choke me.' is used.
Also, I don't think it is portable to let the `#' be at a different
column than the first.

Why not just $1? Also, inside a macro call, arguments should be
quoted, especially $1 etc., ifelse([$1], , :, [$1]).

Same here.
