This fails under cparser 8ec1a761bf62be1028632e5eceda425d9fbeb039 with warning "implicit declaration of function 'foo'" and linker error "undefined reference to `foo'".
It compiles correctly under GCC 10.2.0, Clang 10.0.1, MSVC 19.27.29111 and TinyCC 0.9.27. It also compiles correctly with cparser if you replace #define bar foo with #define bar(x) foo(x).
