According to my references, bsearch() was originally a SysV localism
but is a required library function in ANSI C. So in theory it should
be portable enough ... but I notice we have implementations in
backend/ports for strtol() and strtoul() which are also required by
ANSI C, so apparently some people are or were running Postgres on
machines that are a few bricks shy of a full ANSI library.
I suggest waiting to see if anyone complains. If so, we should be
able to write up a substitute bsearch() and add it to ports/.
