struct target_waitstatus. Change status argument to target_wait to be struct target_waitstatus * instead of int *. * target.h, infrun.c, all targets: Change type of signal arguments to resume(), proceed(), and target_resume() from int to enum target_signal. * All targets (*_wait, *_resume): Change accordingly. * infcmd.c (program_info, signal_command), throughout infrun.c, * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff. * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex signal code stuff right with the new signals would be non-trivial). * inferior.h (stop_signal): Make it enum target_signal not int. * target.c, target.h (target_signal_to_string, target_signal_to_name, target_signal_from_name): New functions. * inftarg.c, target.h (target_signal_to_host, target_signal_from_host, store_waitstatus): New functions. * procfs.c (procfs_notice_signals): Use them. * i960-tdep.c (i960_fault_to_signal): New function, to replace print_fault. * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
