ignoring suffix-specific path search. So if a node was marked .MADE,
then suffix rules would not be applied to it, and we would look for
the file only in the default path, not the suffix-specific path.
XXX: Now that we looked for the suffix, we can save it in the GNode,
but we don't do this yet.
Its not posix compliant and serves very little purpose.
With this change compat and jobs modes are consistent wrt how
they treat each line of a script.
Add support for the '+' command line prefix as required by posix.
Lines prefixed with '+' are executed even when -n is given.
[Actually posix says they should also be done for -q and -t]

Instead of adding MAKE_BOOTSTRAP for hosted environments, i.e., when
you want things simple, instead add MAKE_NATIVE to get those hugely
important features like __RCSID().
It's now possible to build make on some hosts with: cc *.c */*.c
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.
Unfortunately this revealed a deeper problem with the brk_string code.
To fix it:
- remove sharing of the buffer between brk_string invocations
- change the semantics of brk_string so that the argument array
starts with 0, and return the buffer where the strings are
stored
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.
