longjmp predates POSIX by an eon or two. I doubt you need to worry about
it on Unix platforms. (Since we utterly rely on it in the backend,
Postgres wouldn't ever work on a platform without it anyway.)
Less sure about the situation on Windows or Mac, but configure isn't
going to help for those anyway.
