   Hmm.  psql does use readline, but there's no direct dependency on
   curses.  (I verified this by building without curses; it works, here.)
   
   Perhaps there are some implementations of readline that depend on
   curses?  The GNU libreadline I have here appears to use termcap,
   but not curses.  There might be other versions though.
   
   I think it would be possible to extend configure to detect which
   library(s) libreadline depends on, and only include those in the link.
   But that's not something to risk at this stage...

   readline needs terminfo/termcap.  On many Linux systems terminfo support
   is in the [n]curses library.

   Doesn't work here :-) I suspect you are correct, because now that I inspect
   the makefile output more closely, it is libreadline that has the unresolved
   references, not any object file in the source tree.
