Does anyone know why the following code fails with the DMC compiler?

std::cout << __FUNCTION__ << std::endl;

This works with GCC and MSVC++.

__FUNCTION__ seems to be recognized by DMC, but still the code does not
compile.

Thanks

Yes, this works:

#include <iostream>

int main() {
    std::cout << __FUNCTION__ << std::endl;
    return 0;
}

However, this does not:

#include <iostream>

class test {
public:
  test() { std::cout << __FUNCTION__ << std::endl; }
};

int main() {
    test x;

Since the dmc docs say:

| __FUNCTION__
|
|     Same as __FUNC__. Provided for Gnu CC compatibility.

it could be a bug if "Gnu CC" is also intended to mean gcc c++.

Note also that the output of __FUNCTION__ differs from gcc:

gcc prints:             dmc prints:
  test                    test::test
  ~test                   test::~test
