We didn't really want to assume that all platforms are using libbind :-(

i think you could have, at the time, since windows wasn't even a gleam in

i have two suggestions.  first, look at the rest of the current source file,
in case there are other fixes.  second, track changes this source file during
your release engineering process for each new pgsql version.
