to wake up any processes waiting via PIOCWAIT on process exit, and truss
needs to be more aware that a process may actually disappear while it's
waiting.

All Makefiles now use MACHINE_ARCH for the target architecture.
Unification is required for cross-building.

fixed typo: MACHINDE -> MACHINE_ARCH
execvp() in the child branch of a vfork(). Changed to use fork()
instead.
Some of these (mv, find, apply, xargs) might benefit greatly from
being rewritten to use vfork() properly.

some header files (e.g., <err.h>) include <machine/something.h>, and this
will not pick up the right header files, so it may be removed eventually
anyway. But some people who are not willing to build the right way
apparantly want this, so this is for them.
anything other than <sys/*.h>), and unnecessary in most cases. (The
situations where it is necesary can be dealt with by manually-made symlinks,
which is acceptable since they should only occur during testing. Remember:
the tree does not compile well if you do not have matching header files
installed. Half-baked -I directives don't cover enough of the cases.)
Correct usage: one of {-p pid, command} is required.
Open output file when command line is fully analyzed: incorrect `truss -o f'
command does not create an empty file anymore.
change from
ioctl(fd, PIOC<foo>, &i);
to
ioctl(fd, PIOC<foo>, i);
This is going from the _IOW to _IO ioctl macro. The kernel, procctl, and
truss must be in synch for it all to work (not doing so will get errors about
inappropriate ioctl's, fortunately). Hopefully I didn't forget anything :).
said process will not have its event mask cleared (and be restarted) on
the last close of a procfs/mem file for that pid. This reduces the chance
that a truss-monitored process will be left hanging with these bits set
and nobody looking for it.
This is the least-tested change of all of these, I'm afraid.
