/* 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. */ /* { dg-do preprocess } */ /* { dg-options -Wtraditional } */ #define f(x) x #define g(x) x / 2 #define h(a, b) a(b) f(g) (3) /* { dg-bogus "must be used with arguments" } */ f 2 /* { dg-warning "must be used with arguments" } */ f(g) 3 /* { dg-warning "must be used with arguments" } */ h(f, 3) /* { dg-bogus "must be used with arguments" } */
