ncurses-5.7 misses a terminfo entry for the terminal emulator in Emacs 22 (which was released almost two years ago).
Created attachment 191880 [details, diff] Patch from upstream Attached patch adds an entry for eterm-color to the terminfo file. This is part of an upstream patch available at <ftp://invisible-island.net/ncurses/5.7/>.
added to 5.7-r1, thanks
