-       * Mac and DOS support is broken, doesn't even
-         compile.  Multiple display support will probably not provide
-         new Emacs features on these systems, but the multi-tty
-         branch changed a few low-level interfaces, and the
-         system-dependent source files need to be adapted
-         accordingly.  The changes are mostly trivial, so almost
-         anyone can help, if only by compiling the branch and
-         reporting the compiler errors.
