-The bootstrap process makes sure all necessary files are rebuilt
-before it builds the final Emacs binary. Unfortunately, it doesn't
-always work when there are stale files from a previous build in the
-directory tree.
-
-So if 'make bootstrap' fails, it may be necessary first to do 'make
-maintainer-clean' to clear out these stale files. You can then try
-again, starting with `./configure'. (Occasionally the loaddefs.el
-file gets into a bad state due to changes in the Lisp libraries; this
-procedure forces it to be regenerated.)
