/* 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.  */
