and the PrintAddr function for traversing lists. Other general-purpose
utilities inside make(1) can go here, in time.
documentation already adequatedly existed in the description in most
cases. Where it did not, it was added. If no documentation existed
beforehand, then none was added. Some unused dummies for use in the
traversal functions were marked as __unused during the conversion.
Occasionally, local style fixes were applied to lines already being
modified or influenced.
Now make(1) should always build with WARNS=3.

forkbomb from happening, in a dumb and mechanical way.

renaming variables to not shadow libc functions or greater scope locals. Kinda
makes one wonder if the extern ones weren't meant in some of these places :)
The only thing I'd still like to do WRT this is possibly combine rstat and
status in compat.c -- that should be fine, as I do not think the codepaths
will want both around at once.

it, which means that relative paths will be expanded to absolute paths, and
filenames without a path will end up with their absolute path included as
well. This aids tremendously in debugging a build using our make(1) with
multiple Makefile's, such as when there is a syntax error in a file in a
sub-directory as per <bsd.subdir.mk>. Normally we'd end up with just
"Makefile" known about the Makefile in question, which means that an error
would be useless for someone trying to debug their build system, now we
end up with a complete real pathname for the Makefile.
So mostly this is useful in a debugging context, but possibly others too
(I haven't thought of them yet, but they probably are more useful if you
make Dir_FindFile use realpath(3), but that's another story).

through the use of a new build directive, MACHINE_CPU, which contains a
list of the CPU generations/features for which optimizations are desired.
This feature will be extended to cover the ports tree in the future.
Currently OpenSSL provides optimizations for i386, i586 and i686-class
CPUs. Currently it has not been tested on an i386 or i486.
Teach make(1) to provide sensible defaults for MACHINE_CPU if it is not
defined (namely, the lowest common denominator CPU we support for each
architecture). Currently this is i386 for the i386 architecture and ev4
for the alpha. sys.mk also sets the variable as a last resort for
consistency with MACHINE_ARCH and bootstrapping from very old versions of
make.
Benchmarks show a significant speed increase even in the i386 case, with
additional improvements for i586 and i686 systems. For maximum performance
define MACHINE_CPU=i686 i586 i386 in /etc/make.conf.

debugging ports and/or complex Makefiles in such a manner that is basically
a last resort, but is quite effective if the output is well-handled.

make(1) uses sysctlbyname() to find out if it is running on a PC98
machine. This check has been added on 1998/9/9. The MIB variable was
added on 1998/8/31. At that time __FreeBSD_version was 300003. So,
only perform the check *if* __FreeBSD_version is defined and if it's
greater than 300003.
For the record: sysctlbyname was added on 1997/5/30 so this change
automaticly handles that...
that -E only operates for a specified variable. Useful since the -e option
will often pull-in many unwanted variable overrides (esp. in a make world
situation). Uses include overriding BINOWN (which cannot be done by normal
methods or through abuses of MAKEFLAGS) or likely for ports to honour CFLAGS
(provided they're running on a system whose make(1) has this option).

cross compilation work in some edge cases. It also makes cross
