/* K+R rejects use of function-like macros in non-function context.

   ANSI C explicitly permits this (the macro is not expanded).

   We should not warn about this during pre-expansion of arguments,

   since traditional preprocessors don't do pre-expansion, and we get

   the warning anyway during the re-scan pass if and only if it is

   appropriate.  */
