1. make -dx turns on DEBUG_SHELL which causes sh -x to be used where
possible.
2. PrintOnError() is now called when make is stopping due to an error.
This routine reports the curdir and the value of any variables listed
in MAKE_PRINT_VAR_ON_ERROR.
3. Variables set via command line, are propagated to child-makes via
MAKEFLAGS. This behaviour appears to be necessary for POSIX (according
to the GNU folk anyway).
4. Do not reset MAKEFILE when reading ".depend" as this rather eliminates the
usefulness of ${MAKEFILE}.
5. Added ${.newline} as a simple means of being able to include \n in the
result of a :@ loop expansion.
6. Set ${MAKE_VERSION} if defined. Need to come up with a useful value.

Well, it should say 'make core-dumps on any error on the primary makefile'.
This was a result of the new changes to print the path to the parsed
Makefile... Made the code a lot more conservative, plus prepended <progname>:
to each message.
arguments names on one function being swapped (by a previous author).
Do not do any duplicate suppression when a source list is created. Instead:
* OP_MADE protects against trying to make the source multiple times.
* A new OP_MARK flag is introduced to suppress duplicates while expanding
the .ALLSRC variable and .USE targets.
This turns the O(n^2) insertion into O(n) in most cases.
This is tested with a `make build' and some special test cases.
Build a list of `cohorts' as before, but do *not* link each one into all the
parent nodes; instead, copy the `cohort' lists into the stream of targets to
be built inside Make_ExpandUse(). Also do the attribute propagation as a
separate pass after parsing.
This eliminates several O(n^2) algorithms.
Make used to only use the search path for nodes that were pure
sources (not targets of other sources). This has been corrected
and now gnu-autoconf generated Makefiles work in directories other
than the source one.
- Suffix transformation rescanning:
Suffix transformations (.c.o:; cc ...) were only recognized in
the past when both suffixes were members of the suffix list.
Thus a sequence like:
.z.b:
echo ${.TARGET}
.SUFFIXES: .z
would cause .z.b: to be inserted as a regular target (and the main
target in this case). Other make programs always add rules that
start with a period in the transformation list and never consider
them as targets. We cannot do that (consider .depend files) so we
resort to scanning the list of the current targets every time a
suffix gets added, and we mutate existing targets that are now
valid transformation rules into transformation rules. If the
transformed target was also the main target, we set the main target
to be the next target in the targets list.
- ${.PREFIX} should never contain a full pathname
- Fixed gcc -Wall warnings
Major:
- compatMake is now FALSE. This means that we are now running in
full pmake mode:
* rules on dependency lines can be executed in parallel and or
out of sequence:
foo: bar baz
can fire the rule for baz before the rule for bar is fired.
To enforce bar to be fired before baz, another rule needs to be
added. [bar: baz]
* adjacent shell commands in a target are now executed by a single
invocation of the shell, not one invocation of the shell per line
(compatMake can be turned off using the -B flag)
- The -j flag now works... I.e. make -j 4 will fork up to four jobs in
parallel when it can. The target name is printed before each burst
of output caused by the target execution as '--- target ---', when j > 1
- I have changed all the Makefiles so that they work with make -j N, and
I have tested the whole netbsd by:
'make -j 4 cleandir; make -j 4 depend; make -j 4; make -j 4 install'
- I have not compiled or tested this version of make with -DREMOTE.
Dependency rules with `=' in the lhs are parsed as variable assignments.
E.g., the following Makefile fails:
A=a b c d
all: $(A:%=%b)
$(A:%=%b):
@echo $@
