* arch-utils.h (gdbarch_info_init): Declare.
* arch-utils.c: Include "arch-utils.h".
(gdbarch_info_init): Define.
(set_endian, set_architecture, set_gdbarch_from_file)
(initialize_current_architecture): Use gdbarch_info_init.
* rs6000-nat.c (set_host_arch): Ditto.
* cris-tdep.c (cris_version_update, cris_mode_update)
(cris_abi_update): Ditto.
2001-12-19 Jim Blandy <jimb@redhat.com>
* c-lang.c (c_emit_char): Print ASCII 11 as '\v', to match
