+       * image.c: Use ptrdiff_t, not int, for sizes.
+       (slurp_file): Switch from int to ptrdiff_t.
+       All uses changed.
+       (slurp_file): Check that file size fits in both size_t (for
+       malloc) and ptrdiff_t (for sanity and safety).
+
        * fileio.c (Fverify_visited_file_modtime): Avoid time overflow
        if b->modtime has its maximal value.
