That sounds like what I was thinking (unless nm isn't returning any
symbols at all- some shared  libraries work with nm, some don't).

Most platforms that have ifdef's for POSIX in their headers make
provision for handling the more common non-POSIX extensions.  The
way SIGWINCH is ifdef'd in the header I was reading for MacOS X 10.4.3
doesn't leave any way to use _POSIX_C_SOURCE and still use SIGWINCH.

In different versions of the configure script, I've either suppressed
the check for the "darwin" platform, or allowed it to try to set the
standard #define's.  Depending on which I choose, one or the other of
the programs using that configure macro works or not.
