666 /* This is a kludge to make sure emacs can only link against a version of
667 lwlib that was compiled in the right way. Emacs references symbols which
668 correspond to the way it thinks lwlib was compiled, and if lwlib wasn't
669 compiled in that way, then somewhat meaningful link errors will result.
670 The alternatives to this range from obscure link errors, to obscure
671 runtime errors that look a lot like bugs.
