+
+       'sort' race condition fixes.
+
+       Defend against a DoS attack where someone else creates a
+       temporary file with the same name as ours.  Use mkstemp to do
+       this, supplying our own mkstemp if the system doesn't have one.
+
+       Also, fix a race condition during cleanup on hosts without
+       sigaction.
+
+       * src/sort.c (NAME_MAX_IN_DIR): Remove.
+       (sigprocmask, sigset_t): New macros, defined only on older hosts.
+       (caught_signals): New var.
+       (xtmpfopen, tempname): Removed.
+       (create_temp_file): New function, combining the functions of the old
+       xtmpfopen and tempname.  All callers changed.
+       Use mkstemp to create the file.
+       (sighandler): On hosts without sigaction, ignore signals while
+       cleaning up, instead of letting them interrupt cleanup.
+       (main): Initialize caught_signals.  On hosts with sigaction, block all
+       caught signals while handling one.  Remove duplicate code.
+
+       * m4/jm-macros.m4 (jm_MACROS): Use mkstemp replacement if the system
+       lacks mkstemp.  Compile our own tempname.c if we compile our own
+       mkstemp.c, as mkstemp relies on tempname.
