Simple Line Editor

[Eric Norum]

It's already an 'add-on' package but I think that it's not being built as Till suggested.  I ran the script to build this for RTEMS and the Makefile ends up with:
DEFINES =  -DUSE_TERMINFO=1 -DHAVE_TERM_H=1 -DHAVE_CURSES_H=1 -DHAVE_SELECT=1

I don't see any 'configure' option to control the termcap/terminfo/ANSI setting.  Is explicit editing of the generated Makefile the only way to get rid of the
-DUSE_TERMINFO?
