+       * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
+       The plain *_OVERFLOW macros run afoul of GCC bug 49705
+       <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
+       and therefore cause GCC to emit a bogus diagnostic in some cases.

        * image.c: Integer signedness and overflow and related fixes.
        This is not an exhaustive set of fixes, but it's time to
        record what I've got.
