Cannot Compile in g++-6

[Tomius]

Hi rcalxrc08,

Thank you for letting me know this issue.

It seems that I forgot to commit that file, but there was only a using statement in it, like this:

template< bool B, class T = void >
using enable_if_t = typename std::enable_if<B,T>::type;

I first wanted this library to use c++11, not c++14, so I had to define this myself, and I somehow left it there.

Anyway, this issue seems to be fixed with the 2d78f53 commit I just made.
