[Bug c++/16069] New: Bad error message

["igodard at pacbell dot net" <gcc-bugzilla at gcc dot gnu dot org>]

In:

#include    <iostream>
class A{};

template<typename T>
void    Foo(const T& t) {}

int main() {
    A a;
    Foo(std::endl);
    }

you get:

~/ootbc/common/test/src$ g++ foo1.cc
foo1.cc: In function `int main()':
foo1.cc:9: error: no matching function for call to `Foo(<unknown type>)'

"unknown type" is pretty lame; there are actually several types here because endl is an overloaded function. The error is a template resolution ambiguity, and should be reported as such. This is related to bug #16068, which for unknown reasons produces a different (but still bad) message in the same circumstances but when applied to an operator rather than a function.
