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.
- Turn compat mode on by default. It gets turned off when the -j without
  the -B flag is specified. [Thus you can use -j 1 to turn it off].
- Fix malloc -> emalloc as Gordon noted.
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.

from cgd@netbsd:
pull in make.h.  (PAlloc() now uses emalloc(), which is prototyped in
make.h.  If the prototype is not in scope on the Alpha, I see lots
of "cast to pointer from integer of different size" warnings.)
