(_initialize_arm_tdep): install 'othernames' command. (arm_nullified_insn, shifted_reg_val, arm_get_next_pc): New. * configure.in: Check for termios.h, termio.h and sgtty.h. (i[345]86-*-win32*): New host. * configure: Regenerated. * inflow.c: Clean up inclusions. * main.c (main): Check for WINGDB, not WIN32. * printcmd.c (do_examine): Put QUIT test in loop. * remote-hms.c (e7000_load): Delete. (hms_ops): Point to generic_load instead. * remote-hms.c (hms_ops): Point to generic_load. * remote-sim.c (sim_callback_write_stdout): Becomes gdbsim_write_stdout. (gdbsim_load): Call generic_load. * remote-utils.c (gr_load_image): Delete. * ser-unix.c (terminal.h): Include instead of havig own #if tree. (hardwire_flush_input): Reset input buffer too. * source.c (openp): If WIN32 then open file in binary mode. * terminal.h: Configure IO mechanism using autoconf defines if available and not overriden. * utils.c (quit, pollquit, notice_quit): WIN32 check becomes WINGDB check. * config/arm/arm.mt (TDEPFILES): Add remote-rdp.o * config/arm/tm-arm.h (TARGET_BYTE_ORDER): becomes TARGET_BYTE_ORDER_SELECTABLE. (ADDR_BITS_REMOVE): New. (ORIGINAL_REGISTER_NAMES, ADDITIONAL_REGISTER_NAMES): New. (INST_xx): New (FRAME_FIND_SAVED_REGS): Pass the right argument.
