sjg 0828d668af Changes to make MAKEOBJDIRPREFIX useful.
Firstly, we ignore getenv("PWD") if MAKEOBJDIRPREFIX is set so that we always
get the same value for .CURDIR regardless of how make was invoked.

Second, when executing a command we check if it is ${.MAKE} or ${.MAKE:T}
without a preceeding chdir, if so we insert a chdir(${.CURDIR}) so that
the Makefile will be found by the child make.  Note that this behaviour is
dissabled if MAKEOBJDIRPREFIX is not set or if NOCHECKMAKECHDIR is set.
See the comments in main.c for more detail.

With these two changes, one can successfully build usr/src using MAKEOBJDIRPREFIX
allowing the src to be mounted from a CD-ROM.

mycroft f5d7100e26 Nuke `extern int errno;' in code we compile with -Wstrict-prototypes. We get
the correct definition from errno.h.

mycroft ce14db1fcd Fix a bug in the previous. In the `compat' case, we don't actually use the
list of target nodes returned by Make_ExpandUse().  We have to search the
cohorts explicitly while iterating through the tree.  So, tweak CompatMake()
to do this.

christos 4f3cc30bcc This patch fixes the problem introduced in the previous commit where
parents would be get remade, even if children were not really updated
by the commands executed for them. It also makes all the children have
the real modification time set if possible, so it should fix some other
timing weirdnesses...

- collapse childMade and make fields into flags and convert them to bits
  CHILDMADE and REMAKE
- introduce FORCE flag that gets set in all the parents of a child that
  has no sources and does not exist.
- set oodate if the FORCE flag is set, and not if CHILDMADE
- centralize the RECHECK into Make_Recheck() and use this in make.c and compat.c
- use Make_TimeStamp for all child -> parent timestamp propagations

itohy 6aeb72f23f Reduced memory leaks.
I found some more leaks, but are not in inside of iterations.

christos f46f2d693e PR/5210: Hauke Fath: make core dumps with .SHELL
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

christos dd0a1d0814 Add a .MADE directive to indicated that the children of a target are
up-to-date, even when they are not. This is to simulate our current
make install behavior with proper dependencies.

christos 4417c4f61f Reported by cgd: fix .USE directive problems:
1. ${.*} variables did not get expanded in dependencies.
    2. expanded ${.*} variables in .USE dependencies can cause tree
       restructuring; handle it.
    3. in compat mode, expand .USE before evaluating the list of targets,
       instead of doing .USE expansions on demand, because they can cause
       tree restructuring.

christos 6611cb1d0d Updates for POSIX/SVR4 compiling:
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.

christos 61067003d8 Minor:
- ${.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.
