Port --enable-gcc-warnings to GCC 5.1 x86-64
* lib-src/ebrowse.c (dump_sym): * lib-src/hexl.c (main): * src/ccl.c (ccl_driver): * src/character.c (string_escape_byte8): * src/dbusbind.c (xd_retrieve_arg, xd_add_watch): * src/gnutls.c (Fgnutls_boot): * src/gtkutil.c (xg_check_special_colors): * src/image.c (x_build_heuristic_mask): * src/print.c (safe_debug_print, print_object): * src/term.c (produce_glyphless_glyph): * src/xdisp.c (get_next_display_element) (produce_glyphless_glyph): * src/xterm.c (x_draw_glyphless_glyph_string_foreground): Don't use a signed format to print an unsigned integer, or vice versa. GCC 5.1's new -Wformat-signedness option warns about this. * src/image.c (png_load_body, jpeg_load_body): Silence a bogus setjump diagnostic from GCC 5.1 (GCC bug 54561).
