Maybe it should make a human-understandable report of missing functionality at the very end of the configure run: ---- WARNING ---- The following functionalities will be missing in your compilation of Emacs because of missing development libraries (specify -without-FEATURE to omit warning about such a missing feature): jpeg: used for displaying jpeg image files tiff: used for displaying tiff image files xpm: used for displaying xpm image files and color icons alsa: used for playing sounds from within Emacs -- David Kastrup
