-Wzero-as-null-pointer-constant leads to compiler error in g++ #48

As of boost 1.72, I'm getting "error: zero as null pointer constant" when using e.g. boost::chrono::milliseconds. This can IMO be fixed by using nullptr instead.

I've spotted the following places, but there might be more:

duration.hpp:458
duration.hpp:481
duration_put.hpp:216
time_point.hpp:185

Boost is compatible with C++98.

A PR is more than welcome if you manage with this fact.

Seems that NULL can be used to ensure compatibility. Not sure if I'll create a PR.
