arch.c: Don't require ranlib stuff. Not everybody has it.
dir.c: SunOS-4 != Solaris; change #ifdef sun to #if sun && !__svr4__
job.c, compat.c: Don't use 'union wait', use int and the W*() macros.
main.c: Check for uname() == -1; some unames return > 0...
util.c, job.c: Add signal() with BSD semantics for svr4, don't use bsd
sigmask and friends.
- ${.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 $@
var.c: Minor memory leak plugged.
suff.c: Don't add extra sources on the null suffix if it has dependency
lines or commands attached to it [POSIX says so]
This is not the perfect fix. I think that the whole __SYMDEF
checking code should be removed. [I should also teach myself
how to deal with the PR stuff to mark this closed :-)]
1. Honor environment variable $MACHINE if set over uname.machine
2. archives with :: are always out of date, even when they have no children.
3. VAR= a b c # comment, gets the trailing blanks trimmed, unless
escaped by \. I'll have to read the posix manul to make sure that it
is ok to handle escapes here.
The following two patches fix a couple of problems with make(1)
1. Null Suffixes were not being copied, but they were being free'd
This caused rules of the form:
.c:
${CC} ...
to access invalid memory and potentially core dump..
[That was always broken; I did not break that one :-)]
2. My recent fixes to parse ${VAR:%.foo=%.bar} handled the null string
case incorrectly (${VAR:=.c} was broken).
