I don't think this is true.  If you have termios, most of the code
simply works, except that you need to deal with the tputs and its ilk
here and there.

DJGPP doesn't have the termcap capability yet.  Instead, the readline
sources have a few DJGPP-specific hacks to make it work.

I would be interested in making Readline work reasonably well,
including command-line editing etc., on non-Unix systems.  As I said,
it currently works with DJGPP, but requires a small number of ugly
#ifdef's, and some functionality, like arrow keys, isn't supported,
which annoys DJGPP users who aren't hooked on Emacs.
