2021-10-22  Simon J Gerraty  <sjg@beast.crufty.net>

	* configure.in: use_defshell, set both DEFSHELL_INDEX
	and defshell_path if appropriate.
	This makes it easier to use say the KSH specification with
	and alternate path for the shell.
	
	* configure.in compat.c: for SCO we need to force UseShell

	* configure.in: SCO /bin/sh is not usable, provide a list of
	alternatives for use as .SHELL.
	We still have to mark some tests as broken, plus more if we end up
	with ksh as .SHELL.
	Issue a warning about skipped tests.

	* boot-strap: leave TOOL_DIFF to configure

	* configure.in: on SCO native cc is not usable,
	gcc is to be found in /usr/gnu/bin
	and while ancient is at least able to compile bmake.
	Thus we add /usr/gnu/bin to PATH if it exists, and later
	check if $CC would have been found via $PATH.
	If not we set CC to the full path of $CC.
	Also gnu diff is known to support -u, so if it exists use it.

	* configure.in: move getopt to AC_REPLACE_FUNCS
	also add AC_C_INLINE - in an attempt to compile using
	native cc on SCO.

	* configure.in: check for stresep as well as strsep, since we
	define the later to the former if necessary, and if we have to
	provide stresep we also need to provide a prototype.

	* configure.in: we no longer need to worry about
	sys/cdefs.h providing __RCSID which simplifies things quite a bit.

	* make.h: make sure we have __RCSID

	* unit-tests/Makefile.config.in: add TOOL_DIFF so configure
	can control it.

2021-10-20  Simon J Gerraty  <sjg@beast.crufty.net>

	* configure.in: check if timezone Europe/Berlin is supported
	if not try UTC-1
	* configure.in: if .OBJDIR is $srcdir/obj we need to create a
	symlink unit-tests -> ../unit-tests/obj so that
	unit-tests/Makefile.config is put in the right place.
	* refine filtering of .OBJDIR in unit-tests
	
2021-10-16  Simon J Gerraty  <sjg@beast.crufty.net>

	* Fix unit-tests on Minix 3.2.0
	o job.c: do not punt if read of token pipe fails for EAGAIN.
	On Minix at least, we are not ready to read the childExitJob pipe
	when poll says we are.
	There should actually be no reason for this pipe to be
	non-blocking, but while that works fine on {Net,Free}BSD it
	breaks another test case on Minix.
	o unit-tests/Makefile: deal with variants of error messages
	  and use of obj as .OBJDIR

2021-10-14  Simon J Gerraty  <sjg@beast.crufty.net>

	* configure.in: add sigaction to AC_REPLACE_FUNCS
	we also need to check for sigaddset etc just for the benefit of
	sigact.c

	* Add sigact.c as sigaction.c so this "just works".
	This should have been done back when bmake_signal started using
	sigaction (I only just noticed that sigact.c wasn't here ;-)
	Note: I no longer have access to any system where this would matter.

2021-10-13  Simon J Gerraty  <sjg@beast.crufty.net>

	* VERSION (_MAKE_VERSION): 20211011

	* VERSION (_MAKE_VERSION): 20210621
	Merge with NetBSD make, pick up

2004-02-12  Simon J. Gerraty  <sjg@void.crufty.net>

	* arch.c: don't include ranlib.h on ELF systems
	(thanks to Chuck Cranor <chuck@ece.cmu.edu>).

2004-01-18  Simon J. Gerraty  <sjg@void.crufty.net>

2003-12-22  Simon J. Gerraty  <sjg@void.crufty.net>

	* Make portable snprintf safer - output to /dev/null first to
	check space needed.

	* Makefile.in (BMAKE_VERSION): bump version to 20031222
	* Merge with NetBSD make, pick up:
	  o -dg3 to show input graph when things go wrong.
	  o explicitly look for makefiles in objdir if not found in curdir so
	    that errors in .depend etc will be reported accurarely. 
	  o avoid use of -e in shell scripts in jobs mode, use '|| exit $?'
	    instead as it more accurately reflects the expected behavior and
	    is more consistently implemented.
	  o avoid use of asprintf.

2003-09-28  Simon J. Gerraty  <sjg@void.crufty.net>

	* util.c: Add asprintf and vasprintf.

	* Makefile.in (BMAKE_VERSION): bump version to 20030928
	* Merge with NetBSD make, pick up:
	:[] modifier - allows picking words from a variable.

	W flag for :C and :S - allows treating value as one big word.
	
2003-09-12  Simon J. Gerraty  <sjg@void.crufty.net>

	* Merge with NetBSD make
	pick up -de flag to enable printing failed command.
	don't skip 1st two dir entries (normally . and ..) since
	coda does not have them.

2003-09-09  Simon J. Gerraty  <sjg@void.crufty.net>

	* Makefile.in (BMAKE_VERSION): bump version to 20030909
	* Merge with NetBSD make, pick up:
	- changes for -V '${VAR}' to print fully expanded value
	  cf. -V VAR

	- several files got updated 3 clause Berkeley license.
	
2003-08-02  Simon J. Gerraty  <sjg@void.crufty.net>

	* boot-strap: Allow setting configure args on command line.

2003-07-31  Simon J. Gerraty  <sjg@void.crufty.net>

	* configure.in: add --with-defshell to allow sh or ksh
	to be selected as default shell.

	* Makefile.in: bump version to 20030731

	* Merge with NetBSD make 
	Pick up .SHELL spec for ksh and associate man page changes.
	Also compat mode now uses the same shell specs.

2003-07-29  Simon J. Gerraty  <sjg@void.crufty.net>

	* var.c (Var_Parse): ensure delim is initialized.

	* unit-tests/Makefile.in: use single quotes to avoid problems from
	some shells.

	* makefile.boot.in:
	Run the unit-tests as part of the bootstrap procedure.

2003-07-28  Simon J. Gerraty  <sjg@void.crufty.net>

	* unit-tests/Makefile.in: always force complaints from
	${TEST_MAKE} to be from 'make'.

	* configure.in: add check for 'diff -u'
	also fix some old autoconf'isms
	
	* Makefile.in (BMAKE_VERSION): bump version to 20030728.
	if using GCC add -Wno-cast-qual to CFLAGS for var.o

	* Merge with NetBSD make
	Pick up fix for :ts parsing error in some cases.
	Pick unit-tests.

2003-07-23  Simon J. Gerraty  <sjg@void.crufty.net>

	* Makefile.in (BMAKE_VERSION): bump version to 20030723.

	* var.c (Var_Parse): fix bug in :ts modifier, after const
	correctness fixes, must pass nstr to VarModify.

2003-07-14  Simon J. Gerraty  <sjg@void.crufty.net>

	* Makefile.in: BMAKE_VERSION switch to a date based version.
	We'll generally use the date of last import from NetBSD.

	* Merge with NetBSD make
	Pick up fixes for const-correctness, now passes WARNS=3 on
	NetBSD.
	Pick up :ts modifier, allows controlling the separator used
	between words in variable expansion.

2003-07-11  Simon J. Gerraty  <sjg@void.crufty.net>

	* FILES: include boot-strap and os.sh

	* Makefile.in: only set WARNS if we are NetBSD, the effect on
	FreeBSD is known to be bad.

	* makefile.boot.in (bootstrap): make this the default target.

	* Makefile.in: bump version to 3.1.19

	* machine.sh: avoid A-Z with tr as it is bound to lose.

2003-07-10  Simon J. Gerraty  <sjg@void.crufty.net>

	* Merge with NetBSD make
	Pick up fix for PR/19781 - unhelpful error msg on unclosed ${var:foo
	Plus some doc fixes.
	
2003-04-27  Simon J. Gerraty  <sjg@void.crufty.net>

	* Merge with NetBSD make
	Pick up fix for PR/1523 - don't count a library as built, if there
	is no way to build it 

	* Bump version to 3.1.18

2003-03-23  Simon J. Gerraty  <sjg@void.crufty.net>

	* Merge with NetBSD make
	Pick up fix for ParseDoSpecialSrc - we only use it if .WAIT
	appears in src list.

2003-03-21  Simon J. Gerraty  <sjg@void.crufty.net>

	* Merge with NetBSD make (mmm 10th anniversary!)
	pick up fix for .WAIT in srcs that refer to $@ or $* (PR#20828)
	pick up -X which tells us to not export VAR=val via setenv if
	we are already doing so via MAKEFLAGS.  This saves valuable env
	space on systems like Darwin.
	set MAKE_VERSION to 3.1.17

	* parse.c: pix up fix for suffix rules

2003-03-06  Simon J. Gerraty  <sjg@void.crufty.net>

	* Merge with NetBSD make.
	pick up fix for propagating -B via MAKEFLAGS.
	set MAKE_VERSION to 3.1.16

	* Apply some patches from pkgsrc-bootstrap/bmake
	Originally by Grant Beattie <grant@netbsd.org>
	I may have missed some - since they are based on bmake-3.1.12
	
2002-12-03  Simon J. Gerraty  <sjg@void.crufty.net>

	* makefile.boot.in (bmake): update install targets for those that
	use them, also clear MAKEFLAGS when invoking bmake.boot to avoid
	havoc from gmake -w.  Thanks to Harlan Stenn <hstenn@cisco.com>.

	* bmake.cat1: update the pre-formatted man page!

2002-11-30  Simon J. Gerraty  <sjg@void.crufty.net>

	* Merge with NetBSD make.
	pick up fix for premature free of pointer used in call
	to Dir_InitCur().
	set MAKE_VERSION to 3.1.15

2002-11-26  Simon J. Gerraty  <sjg@void.crufty.net>

	* configure.in: determine suitable value for MKSRC.
	override using --with-mksrc=PATH.

	* machine.sh: use `uname -p` for MACHINE_ARCH on modern SunOS systems.
	configs(8) will use 'sun4' as an alias for 'sparc'.

2002-11-25  Simon J. Gerraty  <sjg@void.crufty.net>

	* Merge with NetBSD make.
	pick up ${.PATH}
	pick up fix for finding ../cat.c via .PATH when .CURDIR=..
	set MAKE_VERSION to 3.1.14
	add configure checks for killpg and sys/socket.h

2002-09-16  Simon J. Gerraty  <sjg@void.crufty.net>

	* tag bmake-3-1-13
	
	* makefile.boot.in (bmake): use install-mk
	Also setup ./mk before trying to invoke bmake.boot incase we
	needed install-mk to create a sys.mk for us. 

	* configure.in: If we need to add -I${srcdir}/missing, make it an
	absolute path so that it works for lst.lib too.

	* make.h: always include sys/cdefs.h since we provide one if the
	host does not.
	
	* Makefile.in (install-mk): 
	use MKSRC/install-mk which will do the right thing.
	use uname -p for ARCH if possible.
	since install-mk will setup links bsd.prog.mk -> prog.mk if
	needed, just .include bsd.prog.mk

	* Merge with NetBSD make (NetBSD-1.6)
	Code is ansi-C only now.
	Bug in handling of dotLast is fixed.
	Can now assign .OBJDIR and make will reset its notions of life.
	New modifiers :tu :tl for toUpper and toLower.

Tue Oct 16 12:18:42 2001  Simon J. Gerraty  <sjg@zen.crufty.net>

	* Merge with NetBSD make
	pick up fix for .END failure in compat mode.
	pick up fix for extra va_end() in ParseVErrorInternal.

Thu Oct 11 13:20:06 2001  Simon J. Gerraty  <sjg@zen.crufty.net>

	* configure.in: for systems that have sys/cdefs.h check if it is
	compatible.  If not, include the one under missing, but tell it to
	include the native one too - necessary on Linux.

	* missing/sys/cdefs.h: if NEED_HOST_CDEFS_H is defined, use
	include_next (for gcc) to get the native sys/cdefs.h

Tue Aug 21 02:29:34 2001  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* job.c (JobFinish): Fix an earlier merge bug that resulted in
	leaking descriptors when using -jN.
	
	* job.c (JobPrintCommand): See if "curdir" exists before
	attempting to chdir().  Doing the chdir directly in make (when in
	compat mode) fails silently, so let the -jN version do the same.
	This can happen when building kernels in an object tree and
	playing clever games to reset .CURDIR.

	* Merged with NetBSD make
	pick up .USEBEFORE

Tue Jun 26 23:45:11 2001  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* makefile.boot.in: Give bmake.boot a MAKESYSPATH that might work.

Tue Jun 12 16:48:57 2001  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* var.c (Var_Set): Add 4th (flags) arg so VarLoopExpand can tell
	us not to export the iterator variable when using VAR_CMD context.

Sun Jun 10 21:55:21 2001  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* job.c (Job_CatchChildren): don't call Job_CatchOutput() here,
	its the wrong "fix".

Sat Jun  9 00:11:24 2001  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* Redesigned export of VAR_CMD's via MAKEFLAGS.
	We now simply append the variable names to .MAKEOVERRIDES, and
	handle duplicate suppression and quoting in ExportMAKEFLAGS using:
	${.MAKEOVERRIDES:O:u:@v@$v=${$v:Q}@}
	Apart from fixing quoting bugs in previous version, this allows us
	to export vars to the environment by simply doing:
	.MAKEOVERRIDES+= PATH 
	Merged again with NetBSD make, but the above is the only change.

	* configure.in: added
	--disable-pwd-override		disable $PWD overriding getcwd()
	--disable-check-make-chdir	disable make trying to guess 
		when it should automatically cd ${.CURDIR}

	* Merge with NetBSD make, changes include:
	parse.c (ParseDoDependency): Spot that the syntax error is
	caused by an unresolved cvs/rcs conflict and say so.
	var.c: most of Var* functions now take a ctxt as 1st arg.
	now does variable substituion on rhs of sysv style modifiers.
	
	* var.c (Var_Set): exporting of command line variables (VAR_CMD)
	is now done here.  We append the name='value' to .MAKEOVERRIDES
	rather than directly into MAKEFLAGS as this allows a Makefile to
	use .MAKEOVERRIDES= to disable this behaviour.  GNU make uses a
	very similar mechanism.  Note that in adding name='value' to
	.MAKEOVERRIDES we do the moral equivalent of:
	.MAKEOVERRIDES:= ${.MAKEOVERRIDES:Nname=*} name='val'

Fri Jun  1 14:08:02 2001  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* make-conf.h (USE_IOVEC): make it conditional on HAVE_SYS_UIO_H

	* Merged with NetBSD make
	make -dx can now be used to run commands via sh -x
	better error messages on exec failures.

Thu May 31 01:44:54 2001  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* Makefile.in (main.o): depends on ${SRCS} ${MAKEFILE} so that
	MAKE_VERSION gets updated.  Also don't use ?= for MAKE_VERSION,
	MACHINE etc otherwise they propagate from the previous bmake.

	* configure.in (machine): allow --with-machine=generic to make
	configure use machine.sh to set MACHINE. 

	* job.c (JobInterrupt): convert to using WAIT_T and friends.

	* Makefile.in: mention in bmake.1 that we use autoconf.

	* make.1: mention MAKE_PRINT_VAR_ON_ERROR.

Wed May 30 23:17:18 2001  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* main.c (ReadMakefile): don't set MAKEFILE if reading ".depend"
	as that rather defeats the usefulness of ${MAKEFILE}.

	* main.c (MainParseArgs): append command line variable assignments
	to MAKEFLAGS so that they get propagated to child make's.
	Apparently this is required POSIX behaviour?  Its useful anyway.

Tue May 29 02:20:07 2001  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* compat.c (CompatRunCommand): don't use perror() since stdio may
	cause problems in child of vfork().

	* compat.c, main.c: Call PrintOnError() when we are going to bail.
	This routine prints out the .curdir where we stopped and will also
	display any vars listed in ${MAKE_PRINT_VAR_ON_ERROR}.

	* main.c: add ${.newline} to hold a "\n" - sometimes handy in
	:@ expansion.

	* var.c: VarLoopExpand: ignore addSpace if a \n is present.

	* Added RCSid's for the files we've touched.
	
Thu May 24 15:41:37 2001  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* configure.in:	Thanks to some clues from mdb@juniper.net,
	added autoconf magic to control setting of MACHINE, MACHINE_ARCH
	as well as what ends up in _PATH_DEFSYSPATH.  We now have:

  --with-machine=MACHINE  explicitly set MACHINE
  --with-force-machine=MACHINE  set FORCE_MACHINE
  --with-machine_arch=MACHINE_ARCH  explicitly set MACHINE_ARCH
  --with-default-sys-path=PATH:DIR:LIST  use an explicit _PATH_DEFSYSPATH
  --with-prefix-sys-path=PATH:DIR:LIST  prefix _PATH_PREFIX_SYSPATH
  --with-path-objdirprefix=PATH  override _PATH_OBJDIRPREFIX
 	
	If _PATH_OBJDIRPREFIX is set to "no" we won't define it.

	* makefile: added a pathetically simple makefile to drive
	bootstrapping.  Running configure by hand is more useful.

	* Makefile.in: added MAKE_VERSION, and reworked things to be less
	dependent on NetBSD bsd.*.mk
	
	* pathnames.h: allow NO_PATH_OBJDIRPREFIX to stop us defining
	_PATH_OBJDIRPREFIX for those that don't want a default.
	construct _PATH_DEFSYSPATH from the info we get from configure.

	* main.c: allow for no _PATH_OBJDIRPREFIX, set ${MAKE_VERSION}
	if MAKE_VERSION is defined.
	
	* compat.c: when we bail, print out the .CURDIR we were in.
	
Sat May 12 00:34:12 2001  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* Merged with NetBSD make

	* var.c: fixed a bug in the handling of the modifier :P
	if the node as found but the path was null, we segfault trying to
	duplicate it.

Mon Mar  5 16:20:33 2001  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* Merged with NetBSD make
	
	* make.c: Make_OODate's test for a library out of date was using
	cmtime where it should have used mtime (my bug).

	* compat.c: Use perror() to tell us what really went wrong when we
	cannot exec a command.
	
Fri Dec 15 10:11:08  2000  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* Merged with NetBSD make
	
Sat Jun 10 10:11:08  2000  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* Merged with NetBSD make
	
Thu Jun  1 10:11:08  2000  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* Merged with NetBSD make
	
Tue May 30 10:11:08  2000  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* Merged with NetBSD make
	
Thu Apr 27 00:07:47 2000  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* util.c: don't provide signal() since we use sigcompat.c

	* Makefile.in: added a build target.

	* var.c (Var_Parse): added ODE modifiers :U, :D, :L, :P, :@ and :!
	These allow some quite clever magic.

	* main.c (main): added support for getenv(MAKESYSPATH).

Mon Apr  2 16:25:13 2000  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* Disable $PWD overriding getcwd() if MAKEOBJDIRPREFIX is set.
	This avoids objdir having a different value depending on how a
	directory was reached (via command line, or subdir.mk).

	* If FORCE_MACHINE is defined, ignore getenv("MACHINE").
	
Mon Apr  2 23:15:31 2000  Simon J. Gerraty  <sjg@zen.quick.com.au>

	* Do a chdir(${.CURDIR}) before invoking ${.MAKE} or ${.MAKE:T} if
	MAKEOBJDIRPREFIX is set and NOCHECKMAKECHDIR is not.
	I've been testing this in NetBSD's make for some weeks.

	* Turn Makefile into Makefile.in and make it useful.
	
Tue Feb 29 22:08:00 2000 Simon J. Gerraty  <sjg@zen.quick.com.au>

	* Imported NetBSD's -current make(1) and resolve conflicts.
	
	* Applied autoconf patches from bmake v2

	* Imported clean code base from NetBSD-1.0
