Assuming I am right, I think this means that we need yet another macro (Groans and Cries of Oh No,
not defined is no longer an indicator that
max_digits10 is available (and its values correct).
So do we need
which should be defined by default, and only undefined for those libraries supporting C++0X
std::numeric_limits with correct values like recent GCC - and others (but not <= VC10)?
