Reference forwarding in phoenix::bind does not work in C++11

| Version: | Boost 1.55.0 | Severity: | Problem |

Description
When a user-defined function accepts a non-const reference as an argument, this argument is provided as a const reference by phoenix::bind, even though phoenix::bind is invoked with a non-const lvalue. This only appears in C++11 mode, in C++03 this works as expected.
I've attached the test case and compile errors from GCC 4.8.1.

I might add that this bug affects Boost.Log in a very bad way. It breaks binding user-defined functions as formatters because the output stream is passed to the bound functions by const reference.

I have started to look at this but have not got very far with this yet. I will keep it on my list. John

The test case compiles with gcc 8.2 with Boost 1.68.
