The current trend, as far as I am understanding it, is not to increase
the amount of code in src/port, but actually to reduce it and to rely
a maximum on what modern platforms offer. See for example the recent
discussion about rint and numeric rounding here:

We are keeping rint around because MSVC just added it recently in
MS2013 even if the POSIX spec has it for a long time, but I am sure
that we would drop it asap from the code tree if we could.
