Editline provides readline/[readline.h,history.h] which provide a subset of the readline API and (I've checked) contain all of the functions that ghci uses. One possiblility is to add a configure --with-libedit flag to the readline package which would permit linking against libedit and #ifdef out all functions that it doesn't support. Note that the package already #defines HAVE_READLINE_4 and HAVE_READLINE_5 to permit compiling against multiple versions of readline, so adding HAVE_GNU_READLINE or HAVE_LIBEDIT wouldn't be much worse, IMHO.
