__CONCAT("foo","bar");
actually works to concantate strings, it's because the preprocessor expands
it into "foo""bar" as separate strings, and then ANSI string concatenation
is performed on that. It's more straightforward to just use ANSI string
concatenation directly, and newer GCCs complain (rightly) about misuse
of token pasting.
