* signals.c: New file.
* Makefile.in: Add signals.o. * target.c (struct signals, target_signal_to_name) (target_signal_from_name, target_signal_from_host) (do_target_signal_to_host, target_signal_to_host_p) (target_signal_to_host, target_signal_from_command): Move to signals.c. (initialize_targets): Move check of struct signals to... * signals.c (_initialize_signals): Here.
