Actually, my local tests still include 5.51 and 5.64 but not 5.82.
The issue occurs with both of these compilers. It stems from
the fact that the compiler doesn't really distinguish between

template<class T>
f(T &t)


template<class T>
f(const T & t)

As this is a well know problem already addressed in other libraries
I had hoped that the original author would find it easy to fix.

This is the way I set things up some time ago and I haven't been
motivated to "upgrade" it.
