ChangeLog since bmake-20240108

2024-03-10  Simon J Gerraty  <sjg@beast.crufty.net>

	* boot-strap: tests can take a long time; use a cookie to
	skip them if bmake has not been updated since tests last
	ran successfully.

	* Makefile: Cygwin handles MANTARGET man

	* unit-tests/Makefile: set BROKEN_TESTS for Cygwin

2024-03-09  Simon J Gerraty  <sjg@beast.crufty.net>

	* VERSION (_MAKE_VERSION): 20240309
	Merge with NetBSD make, pick up
	o set .ERROR_EXIT to the exit status of .ERROR_TARGET
	this allows a .ERROR target to ignore the case of
	.ERROR_EXIT==6 which just means that the build actually
	failed somewhere else.

2024-03-04  Simon J Gerraty  <sjg@beast.crufty.net>

	* VERSION (_MAKE_VERSION): 20240303

	* var.c: on IRIX we need both inttypes.h and stdint.h

2024-03-01  Simon J Gerraty  <sjg@beast.crufty.net>

	* VERSION (_MAKE_VERSION): 20240301
	Merge with NetBSD make, pick up
	o export variables with value from target scope
	when appropriate.

2024-02-12  Simon J Gerraty  <sjg@beast.crufty.net>

	* VERSION (_MAKE_VERSION): 20240212
	Merge with NetBSD make, pick up
	o remove unneeded conditional-compilation toggles
	INCLUDES, LIBRARIES, POSIX, SYSVINCLUDE, SYSVVARSUB,
	GMAKEEXPORT NO_REGEX and SUNSHCMD

	* configure.in: add check for regex.h

	* var.c: replace use of NO_REGEX with HAVE_REGEX_H

2024-02-04  Simon J Gerraty  <sjg@beast.crufty.net>

	* VERSION (_MAKE_VERSION): 20240204
	Merge with NetBSD make, pick up
	o var.c: fix some lint (-dL) mode parsing issues

2024-02-02  Simon J Gerraty  <sjg@beast.crufty.net>

	* VERSION: (_MAKE_VERSION): 20240202
	Merge with NetBSD make, pick up
	o make.1: note that arg to :D and :U can be empty
	o var.c: $$ is not a parse error when .MAKE.SAVE_DOLLARS=no

mk/ChangeLog since bmake-20240108

2024-03-09  Simon J Gerraty  <sjg@beast.crufty.net>

	* install-mk (MK_VERSION): 20240309

	* meta.sys.mk: _metaError: if .ERROR_EXIT == 6, we do not
	want to save the .ERROR_META_FILE

2024-02-20  Simon J Gerraty  <sjg@beast.crufty.net>

	* install-mk (MK_VERSION): 20240220

	* sys.dirdeps.mk, dirdeps-targets.mk, init.mk:
	do not set .MAIN: dirdeps in sys.dirdeps.mk
	dirdeps-targets.mk will do that for top-level builds
	and init.mk will do it for others.
	This allows a Makefile which has no need of 'dirdeps' to
	set .MAIN for itself and "just work".

2024-02-18  Simon J Gerraty  <sjg@beast.crufty.net>

	* bsd.*.mk: for makefiles that get a bsd. symlink,
	use _this in  multiple inclusion tags since .PARSEFILE will not
	DTRT when such a makefile is included directly by Makefile and
	automatically (without bsd. prefix).
	Since we cannot guarantee that our sys.mk will be used, we provide
	a default _this in each makefile that gets a bsd. prefix such that
	the value is the same regardless of bsd. prefix.

	* subdir.mk: drop the !target guard on $SUBDIR_TARGETS

2024-02-12  Simon J Gerraty  <sjg@beast.crufty.net>

	* install-mk (MK_VERSION): 20240212

	* SPDX-License-Identifier: BSD-2-Clause
	Add SPDX-License-Identifier to inidicate that I consider
	my copyright on any of these makefiles equivalent to BSD-2-Clause

	* autoconf.mk: allow for configure.ac as currently recommended

	* subdir.mk: support @auto
	which is replaced with each subdir that
	has a [Mm]akefile.

	* subdir.mk: include local.subdir.mk if it exists.

	* subdir.mk: rework to handle .WAIT

2024-02-11  Simon J Gerraty  <sjg@beast.crufty.net>

	* subdir.mk: _SUBDIRUSE report the target we are entering subdirs for.

2024-02-10  Simon J Gerraty  <sjg@beast.crufty.net>

	* prog.mk: treat empty SRCS the same as undefined

2024-02-02  Simon J Gerraty  <sjg@beast.crufty.net>

	* Avoid undefined errors in lint (-dL) mode

	* man.mk (CMT2DOC_FLAGS): note that -mm does mdoc(7)

2024-01-28  Simon J Gerraty  <sjg@beast.crufty.net>

	* install-mk (MK_VERSION): 20240128

	* FILES: add ccm.dep.mk for C++ modules
	add suffixes.mk for common location for generic SUFFIX rules.

	* auto.dep.mk autodep.mk meta.autodep.mk: include ccm.dep.mk
	replace OBJ_EXTENSIONS with OBJ_SUFFIXES

	* autodep.mk: leverage CXX_SUFFIXES for __depsrcs
	and update style (spaces around = etc)

	* init.mk: add OBJS_SRCS_FILTER to filter SRCS when
	setting OBJS

	* meta2deps.py: handle multiple ./ embedded in path better.

# Options are normally listed in either OPTIONS_DEFAULT_{YES,NO}
# We convert these to ${OPTION}/{yes,no} in OPTIONS_DEFAULT_VALUES.
# We add the OPTIONS_DEFAULT_NO first so they take precedence.
# This allows override of an OPTIONS_DEFAULT_YES by adding it to
# OPTIONS_DEFAULT_NO or adding ${OPTION}/no to OPTIONS_DEFAULT_VALUES.
# An OPTIONS_DEFAULT_NO option can only be overridden by putting
# ${OPTION}/yes in OPTIONS_DEFAULT_VALUES.
# A makefile may set NO_* (or NO*) to indicate it cannot do something.
# User sets WITH_* and WITHOUT_* to indicate what they want.
# We set ${OPTION_PREFIX:UMK_}* which is then all we need care about.
