| This is what you always will have to do.  C99 demands that these are
| macros.  You'll replace them with template functions after undefining
| the macros.  There is not more correct way.

Where should we put those? In the global namespace or in the std::?

Strictly speaking, we're not allowed to put them in the global
namespace.
