I'll add a small section to the documentation with an constexpr example.
The (automatically generated?) API reference documentation already includes
the BOOST_CONSTEXPR in the data-types member functions which should be
self-explanatory. I'll ping you when I update the PR and we can discuss
there how to improve the documentation further but basically either you can
use Boost.Units in constant expressions or you can't.

I have some unit-tests but removed them because I wasn't able to enable
them only for compilers with constexpr support (otherwise they will fail to
compile). Boost.Build/Boost.Test documentation wasn't very helpful in this
regard. I just went through Boost.Array develop branch and found:

Should I implement the constexpr tests in a similar manner or do anything

I'll add "Boost.Units has gained constexpr support." to the commit message.

I was just following the boy scout rule but will revert them.
I won't create a new pull-request with these but I since navigating the
code in a 80char terminal was a bit unpleasant I would be happy if you
consider some of them in the future.
