        * Version 5.3.0.

+
+       Signal-handling cleanup for coreutils.  Here are the highlights:
+
+        - csplit sometimes failed to remove files when interrupted.
+        - csplit didn't clean up if two signals arrived nearly simultaneously.
+        - install -s would infloop on System V if SIGCHLD was ignored.
+        - ls could incorrectly restore color if multiple signals
+          arrived nearly simultaneously.
+
+       * src/csplit.c (sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]:
+       Define.
+       (filename_space, prefix, suffix, digits, files_created, remove_files):
+       Now volatile.
+       (caught_signals): New var.
+       (cleanup): Block signals while deleting all files.
+       (cleanup_fatal, handle_line_error, regexp_error):
+       Mark with ATTRIBUTE_NORETURN.
+       (create_output_file, close_output_file, interrupt_handler):
+       Block signals while changing the number of output files,
+       to fix some race conditions.
+       (delete_all_files): Do nothing if remove_files is zero.
+       Clear files_created.
+       (main): Don't mess with signals until after argument processing
+       is done.
+
+       * src/csplit.c (main): Rewrite signal-catching code to make it
+       similar to other coreutils programs.  When processing signals,
+       block all signals that we catch, but do not block signals that we
+       don't catch.  Avoid problems with unsigned int warnings.
+       * src/ls.c (main): Likewise.
+       * src/sort.c (main): Likewise.
+
+       * src/csplit.c (interrupt_handler):
+       Use void, not (obsolete) RETSIGTYPE.
+       * src/shred.c (sigill_handler, isaac_seed_machdep): Likewise.
+
+       * src/csplit.c (interrupt_handler) [defined SA_NOCLDSTOP]:
+       Use simpler "signal (sig, SIG_DFL)" rather than sigaction equivalent.
+       * src/ls.c (sighandler) [defined SA_NOCLDSTOP]: Likewise.
+       * src/sort.c (sighandler) [defined SA_NOCLDSTOP]: Likewise.
+       * src/nohup.c (main) [!defined _POSIX_SOURCE]: Likewise, except
+       for SIG_IGN.
+       * src/tee.c (main) [!defined _POSIX_SOURCE]: Likewise.
+
+       * src/install.c: Include <signal.h>.
+       (main) [defined SIGCHLD]: Set SIGCHLD handler to the default, if -s is
+       given, since System V fork+wait does not work if SIGCHLD is ignored.
+
+       * src/ls.c (sighandler) [!defined SA_NOCLDSTOP]: Reset signal
+       handler to self, not to SIG_IGN, since SIGTSTP can be received
+       more than once.
+       (main): Use SA_RESTART, as that is simpler than checking for EINTR
+       failures all over the place.

        * src/remove.c (is_empty_dir): Clarify comment.
 
        * man/help2man: Accept new option: --program-name=NAME, so that we
