[Bug c++/29332] New: No error given for derived-to-private-base conversion in default arg.

["widman at gimpel dot com" <gcc-bugzilla at gcc dot gnu dot org>]

For the following case: 

// line 1
class A {};
class B : private A { };

extern B b;

void f( A & = b); // ERROR

A & a = b; // ERROR

... g++ issues only one error:

t.cpp:9: error: 'A' is an inaccessible base of 'B'

... but it should also complain about the default arg.

Incidentally, this example was boiled down from code in a real project.
