provide a way to reset setproctitle.

like zsh, have jobs -Z do setproctitle

Don't cast the value returned from *malloc. No change to compiler output.

Don't depend on common declarations.

Welcome to the 21th century csh: retire "ptr_t" now that we have "void *"

Remove Free, s/xfree/free/.

Standard C says that free should be a no-op for a NULL pointer, so
we don't need an extra function to do this.

While here, add an XXX about a wrong sounding comment

WARNS=6 [-Wconversion]

sync with /usr/bin/time, use CLOCK_MONOTONIC

no need to have cshbool; just make them int

PR/36650: Michael van Elst: Get rid of bool, because csh uses bool as a small
int.

Rename bool -> cshbool; despite the name, bool actually holds values other
than 0 or 1. Fixes PR/36650.

exposure of bool elsewhere in the code requires the addition of stdbool;
in addition, proc.c cleverly has a variable that was initially defined "int",
but had in the actual declaration "bool". oops.

No functional changes. Cleanup time printing code so it can be used
elsewhere in the tree.

sprinkle a little const, and now everything compiles with WARNS=3

make signal range check consistent.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22249, verified by myself.

use strtol() for better error handling in builtin kill (Peter Jeremy)

Rename `sigset' locals to avoid symbol shadowing warning.

__STDC__ is always defined on NetBSD.

fix WARNS=2

ANSIfication and KNF improvements by Petri Koistinen in bin/13689,
with some fixes by me.

eliminate nested extern decls.

Remove a bogus whitespace match in the builtin kill(1)'s `-s' parsing;
noticed by Chris Demetriou.

fix incorrect operation caused by the previous checkin.

Fix unaligned access memory problem introduced from the -s fix.
