Building readline 4.2a, I get this in the output from "./configure
--with-curses" (note trailing space on first line):

> checking which library has the termcap functions... using 
> ./configure: test: =: unary operator expected
> ./configure: test: =: unary operator expected
> ./configure: test: =: unary operator expected
> ./configure: test: =: unary operator expected
> checking configuration for building shared libraries... supported

It seems to result from this part of configure ($bash_cv_termcap_lib
is empty and unquoted):

Autoconf bug or readline build bug?  Or does --with-curses need an
=argument?  Is it a problem for bash_cv_termcap_lib to be empty?
