        * libc/include/signal.h (SIG_IGN, SIG_DFL, SIG_ERR): Change
        to use _sig_func_ptr type casted constants.
        (_sig_func_ptr): Typedef moved to sys/signal.h.
        * libc/include/sys/signal.h (_sig_func_ptr): Typedef added.
        For __rtems, use POSIX definition, otherwise default to ANSI.
        * libc/sys/linux/sys/signal.h (_sig_func_ptr): Typedef added.
