2024-04-30 Simon J Gerraty <sjg@beast.crufty.net>

• VERSION (_MAKE_VERSION): 20240430

Merge with NetBSD make, pick up
o main.c: ensure '.include <makefile>' respects MAKESYSPATH.
Dir_FindFile will search .CURDIR first unless ".DOTLAST" is seen.

2024-04-28 Simon J Gerraty <sjg@beast.crufty.net>

• VERSION (_MAKE_VERSION): 20240428

Merge with NetBSD make, pick up
o simplify freeing of lists
o arch.c: trim pointless comments
o var.c: delay variable assignments until actually needed
don't reallocate memory after evaluating an expression, result is
almost always short-lived.

2024-04-26 Simon J Gerraty <sjg@beast.crufty.net>

• VERSION (_MAKE_VERSION): 20240426

Merge with NetBSD make, pick up
o job.c: in debug output, print the directory in which a job

2024-04-24 Simon J Gerraty <sjg@beast.crufty.net>

• VERSION (_MAKE_VERSION): 20240424

Merge with NetBSD make, pick up
o clean up comments, code and tests

2024-04-23 Simon J Gerraty <sjg@beast.crufty.net>

• VERSION (_MAKE_VERSION): 20240422

Merge with NetBSD make, pick up
o var.c: avoid LazyBuf for :*time modifiers.
LazyBuf's are not nul terminated so not suitable for passing to
functions that expect that. These modifiers are used sparingly so
an extra allocation is not a problem.

Merge with NetBSD make, pick up

• VERSION (_MAKE_VERSION): 20240414

Merge with NetBSD make, pick up
o parse.c: print -dp debug info earlier so we see which
.if or .for line is being parsed.

• VERSION (_MAKE_VERSION): 20240404

Merge with NetBSD make, pick up

• VERSION (_MAKE_VERSION): 20240314

Add/Improve support for Cygwin
o uname -s output isn't useful so allow configure to
set FORCE_MAKE_OS - to force the value of .MAKE.OS
and use Cygwin which matches uname -o
o fix some unit-tests for Cygwin

• configure.in: use_makefile=no for Cygwin et al.

NOTE: bmake does not support Cygwin and likely never will,

mk/ChangeLog since bmake-20240309

2024-04-24 Simon J Gerraty <sjg@beast.crufty.net>

• meta.autodep.mk: do not override start_utc

2024-04-18 Simon J Gerraty <sjg@beast.crufty.net>

• sys.dirdeps.mk: set defaults for DEP_* at level 0 too.

These help when first include of Makefile.depend happens in a leaf
dir.

• install-mk (MK_VERSION): 20240414

2024-04-09 Simon J Gerraty <sjg@beast.crufty.net>

• install-mk (MK_VERSION): 20240408

• init.mk: allow for _ as well as . to join V

and Q from QUALIFIED_VAR_LIST and VAR_QUALIFIER_LIST.

• progs.mk: avoid overlap between PROG_VARS and

init.mk's QUALIFIED_VAR_LIST since PROG would also
match its VAR_QUALIFIER_LIST,
libs.mk does not have the same issue.

• subdir.mk: _SUBDIRUSE for realinstall should run install

remove include of ${.CURDIR}/Makefile.inc that can be done via
local.subdir.mk where needed

• own.mk: do not conflict with man.mk

2024-03-19 Simon J Gerraty <sjg@beast.crufty.net>

• install-mk (MK_VERSION): 20240314
