to override @-prefixed commands in Makefiles. It is especially useful for
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.
I'll update the manpage after dinner. ;-)

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...
It appears that make fails to read the global symbol table of the archive file,
making it think that the library needs to be rebuilt.

more subtle about saying that VPATH is for backward(s) compatibility.

improve portability since we've lost portability in several other chunks
of make code (err(), sysctlbyname(), probable more).

"Make no longer properly parses archive files, so using archive members
as make targets, as described in PSD:12 section 4.2, does not work."
Really should be merged into 3.3 before we ship if we can..

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).

Please note that the extent to which these patches work is largely
dictated by how well our tool chains support the cross compilation.

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

This case did not need to be tested when RANLIBMAG was defined
(as when in an `aout' environment) because Arch_StatMember() treated
the two cases of the library not being present and a member of
the library not being present the same way, forcing a rebuild
of the library. Since in the ELF environment we don't look inside
archive libraries we now need to check if the archive library is
present in order to determine its `out-of-date'-ness.

option lets make look inside archive libraries when determining if a
library is out-of-date. I don't think that make should look inside
files, so this fix effectively tells it not to. If the decision is
made (by someone else) that make _should_ be doing this, it will need
to be taught how to recognise elf archive libraries.

says it pretends to make.
This bug was apparently harmless except for normal cases involving
.ORDER statements when it made debugging of -jN using -n very
confusing. E.g., for:
.ORDER: beforedepend .depend
depend: beforedepend .depend
where beforedepend depends on something so that it is not initially
up to date, `make [-n] -j2 depend' causes `make' to wait for itself
to make beforedepend. This works fine without -n. The job to make
beforedepend has normally been started, and beforedepend is marked
as made when the job completes. However, with -n, the pseudo-job
for making beforedepend has normally completed, and in any case
there was no chance of beforedepend being marked as made. `make'
actually exited almost immediately with status 0 instead of waiting
forever.
