I will try some tests with clang. As for other compilers, I just do not 
have others to test against. if there are other compilers which have a 
free version that I can use I will do so.

That works correctly in the library for gcc and VC++. Evidently the code 
that tests, which uses an expression of &A::value, is accepted by those 
compilers. Is it illegal to take the address of a static const data 
member in C++ ?
