* configure.ac: Check for TARGET_CFLAGS initialization before we initialize it ourselves (sigh). Move a few modifications to TARGET_CFLAGS to be unconditional (extra warning flags, loop alignment, i386 CPU extensions, GCC 4.4 eh_frame) * gettext/gettext.c (grub_gettext_delete_list): Add `void' argument. * term/i386/pc/at_keyboard.c (keyboard_controller_wait_untill_ready): Likewise. (keyboard_controller_led): Rename `led_status' paramter to avoid name conflict.
