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

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.
