Assume POSIX 1003.1-1988 or later for signal.h.
Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN, SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these. * admin/CPP-DEFINES (SIGALRM, SIGCHLD, SIGHUP, SIGKILL, SIGPIPE, SIGQUIT): Remove. (SIGTRAP): Remove this one too, as config.h no longer defines it. * admin/merge-gnulib (GNULIB_MODULES): Add sig2str. * configure.ac (PTY_OPEN, PTY_TTY_NAME_SPRINTF): Use SIGCHLD rather than SIGCLD. * lib/sig2str.c, lib/sig2str.h, m4/sig2str.m4: New files, from gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * lib/makefile.w32-in (GNULIBOBJS): Add $(BUILD)/sig2str.$(O). * src/process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>. (deleted_pid_list, Fdelete_process, create_process) (record_child_status_change, handle_child_signal, deliver_child_signal) (init_process_emacs, syms_of_process): Assume SIGCHLD is defined. (parse_signal): Remove. All uses removed. (abbr_to_signal): New static function. (Fsignal_process): Use it to convert signal names to ints. * src/sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than kill (getpgrp (), ...). (emacs_sigaction_init): Assume SIGCHLD is defined. (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL, SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more. * src/syssignal.h (EMACS_KILLPG): Remove. All uses replaced by 'kill' with a negative pid. (SIGCHLD): Remove definition, as we now assume SIGCHLD. * src/w32proc.c (sys_kill): Support negative pids compatibly with POSIX. Fixes: debbugs:13026
