[Bug c++/17207] New: No warning for nonsense template

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

struct D{};
template<typename T>
D& Foo(D& d) { return d;}
int main() {
    D d;
    Foo(d);
    return 0;
    }

gets you:

~/ootbc/common/test/src$ g++ foo1.cc
foo1.cc: In function `int main()':
foo1.cc:6: error: no matching function for call to `Foo(D&)'


which is dine - but if you take out the call then it compiles. As the function can *never* be called the declaration is nonsense and should be flagged at declaration.
