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:
http://www.postgresql.org/message-id/flat/20150320194337(dot)2573(dot)72944(at)wrigleys(dot)postgresql(dot)org#20150320194337(dot)2573(dot)72944@wrigleys.postgresql.org
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.
