Are you sure it's complaining about readline's library, and not
readline's header files? That rather random --with-libs list draws my
suspicion, particularly since it doesn't parallel your --with-includes
list.

That's pretty normal --- configure likes to try to compile things like
#ifdef SYMBOL
choke me
#endif
to find out whether SYMBOL is defined. (If it is, this'll draw a
compile error, else not.) Elegance is not really something autoconf
puts high priority on ...

No, I doubt that.

And that too. You'd need to show some actual evidence, and not a highly
abstracted summary, to convince anyone that you've found a configure
bug.
