My reading of DR 147, makes this invalid code as foo::foo names the
constructor.

I would argue that in 3.4.3.1.2 the constructor is not an acceptable lookup
result, since it would result in the code being invalid.
Additionally, the following use of a type alias (where the constructor is
clearly not an acceptable lookup result) does not compile on my g++-4.7.1:
struct foo { using bar = foo::foo::foo; };

GCC, clang, ICC and MSVC all say this is not a bug and the name is a
constructor name in this context.

This was clarified by Core DR 1310 https://wg21.link/cwg1310
foo::foo names the constructor, and so can only be used to declare the
constructor as a friend, or in a using-declaration for inheriting constructors.
