I noticed the makefile in the libpq dir made symlinks to a handful of .c
files in src/port and references one .h. Aside from those, which I could
simply copy into the libpq dir, is there anything inside the libpq dir that
is changed by the configure script that I can't manage myself? Honestly,
this really doesn't need to be fancy - (hold your nose) it's fine/preferable
to have all the libpq .o's can be linked with myapp.c into a single binary
myapp.

I don't see this as an issue... the mysql code in place now is very old -
from the 3.2x days - but works fine to connect to an up-to-date mysql server.
Unless there is a serious enough issue that demands an update (and perhaps
not even then - the app will always run on a protected network), it will
likely remain as-is until the app is overhauled, replaced or abandoned.

Possibly, but very unlikely.
