Error on include "not all overloads are accessible"

[devinsodhi]

On line 16 in the file Proxyrole.h , 'using QObject::QObject;' breaks the build with the above error.

I specifically only tested on msvc2013, because i m using another lib that requires that i stay in that kit.

Removing the statement seems to fix the issue and the code subset i am experimenting with still works, but I haven't verified that it breaks something else.

Is my fix workable? asking if it doesn't affect newer compilers.
