 * Where shall we look for an include file?

 * 2. Try . and ../include and ../../include
 * 3. Try D and D/../include and D/../../include
 *    where D is the directory from where we are loading the current file.
 * 4. Try KD/include and KD/#/include where KD = DATADIR/KEYMAPDIR.
 *
 * Expected layout:
 * KD has subdirectories amiga, atari, sun, i386, include
 * KD/include contains architecture-independent stuff
 * like strings and iso-8859-x compose tables.
 * KD/i386 has subdirectories qwerty, ... and include;
 * this latter include dir contains stuff with keycode=...
 *
 * (Of course, if the present setup turns out to be reasonable,
 * then later also the other architectures will grow and get
 * subdirectories, and the hard-coded i386 below will go again.)
 *
 * People that dislike a dozen lookups for loadkeys
 * can easily do "loadkeys file_with_includes; dumpkeys > my_keymap"
 * and afterwards use only "loadkeys /fullpath/mykeymap", where no
 * lookups are required.
