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).

With rev 1.7 one cannot build src/bin/sh -- because make fails to create

binaries.

build tool itself, is built with the original make during buildworld).
The problem seems to be that in str_concat(), the string is not
terminated when the length of the second string is 0.
This apparently can happen during null suffix rule processing.

Never to generate an error since the second expression should never be

However, this was not the case. The above fails with the current
make(1) if TEST is undefined. This patch fixes the above and many
similar cases.

remove the concept of a 'maintainer' of our make. there really isn't a
need for any one committer to hold an exclusive lock or serve as a filter

src/sys/modules/if_ef and possibly other things. I tested the build with
a make based on rev. 1.26, and it worked fine. Since I'm not particularly
inclined to figure out what's going on with this, it's probably prudent
just to back it out for now.

.endif statements but can't be placed in .elif. Basically, the problem
was that ParseSkipLine() didn't handle comments the same way that
ParseReadLine() did, and thus you had errors with comments that are on a
conditional line (i.e. "^.") rather than a non-conditional line.

Adding null suffix rules would fail when a rule for the same source was

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.
