Header is imcompatible with c++

[hq6]

The header is not c++ friendly.

Reproducing the problem

Put the following program into a file called main.cc

#include "mpscq.h"
int main(){}

Compile with g++ -c main.cc and get multiple errors that look like this.

usr/lib/gcc/x86_64-linux-gnu/4.9/include/stdatomic.h:68:9: error: ‘_Atomic’ does not name a type
 typedef _Atomic __UINT_FAST32_TYPE__ atomic_uint_fast32_t;
         ^
/usr/lib/gcc/x86_64-linux-gnu/4.9/include/stdatomic.h:69:9: error: ‘_Atomic’ does not name a type
 typedef _Atomic __INT_FAST64_TYPE__ atomic_int_fast64_t;

This is actually something that bothers me in general in C++. Since this is a compiler-provided header, I kinda wished it worked fine on both languages.

I agree that this is a silly compiler issue, but I think as our thread on the #8 shows, there are many solutions to achieving compatibility with C++, and I think it would make this implementation more broadly useable.
