Interesting/relevant changes since bmake-20230909 * VERSION (_MAKE_VERSION): 20240106 Merge with NetBSD make, pick up o fix duplicate progname when reporting an unknown target o unit tests for Cmd_Exec using temp file * VERSION (_MAKE_VERSION): 20240105 Merge with NetBSD make, pick up o main.c: Cmd_Exec write cmd to a file if too big avoid blowing commandline/env limits * VERSION (_MAKE_VERSION): 20240101 o util.c: flesh out more of strftime * configure.in: add --with-bmake-strftime it is not a full implementation but enough to pass all the unit-tests. * parse.c: LoadFile do not append \n to empty buffer. * VERSION (_MAKE_VERSION): 20231230 Merge with NetBSD make, pick up o simplify memory allocation for string buffers o fix declared types of list nodes o suff.c: clean up freeing of suffixes o var.c: simplify debug message for the ':@var@...@' modifier clean up variable handling * VERSION (_MAKE_VERSION): 20231226 Merge with NetBSD make, pick up o compat.c: ensure make's output is correctly ordered with that of the target when not going to a tty o main.c: check for shellPath whether to call Shell_Init() * VERSION (_MAKE_VERSION): 20231224 Merge with NetBSD make, pick up o compat.c: check for shellPath whether to call Shell_Init() tweak the unit test to detect the bug thus fixed. o make.1: do not claim .SHELL is only used by jobs mode. * VERSION (_MAKE_VERSION): 20231220 Merge with NetBSD make, pick up o str.c: speed up pattern matching in the ':M' modifier o var.c: fix confusing debug logging when deleting a variable use consistent debug messages style when ignoring variables * VERSION (_MAKE_VERSION): 20231210 Merge with NetBSD make, pick up o var.c: avoid segfault on empty :C match expression explain in debug log why variable assignment is ignored. * VERSION (_MAKE_VERSION): 20231208 Merge with NetBSD make, pick up o var.c: ensure fromCmd is set correctly for variables set on command line. * VERSION (_MAKE_VERSION): 20231124 Merge with NetBSD make, pick up o main.c: cleanup processing of -j fix lint warning about strchr o var.c: more accurate error message for invalid ':mtime' argument cleanup :[...] modifier avoid reading beyond substring when comparing o unit-tests cover all cases of :mtime, test and explain exporting of variables o cleanup comments * bsd.after-import.mk (ECHO_TAG): FreeBSD no longer uses $FreeBSD$ tag, so avoid adding it. mk/ChangeLog since bmake-20230909 * dirdeps.mk: for MAKE_VERSION 20240105 we do not have the same limits on command line length, so skip export of lists to env. * jobs.mk: avoid C suffix in JOB_MAX_C if factor is floating point. This keeps JOB_MAX numeric incase another makefile does comparisons. * gendirdeps.mk: if META_XTRAS is passed to us, add to META_FILES

# When a dynamic variable (such as .TARGET) is evaluated in the global

|
# resolved at a later point.

# This test covers the code in Var_Parse that deals with DEF_UNDEF but not
|

# DEF_DEFINED for dynamic variables.
