The warnings appear to be a bug in that (extremely old) compiler
version; the expressions involved clearly are constant expressions.
Also, that compiler version will very shortly (hopefully within a
couple of weeks) not work at all, because it lacks C++14 support.
And the change itself does not make the code better in any other way.
So I think this change should not be made.
