- It is opt-out for now so as to give it maximum testing, but it may be
turned opt-in for stable branches depending on the consensus. You
can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
It is harmless to steal the knob as SSP symbols have been provided
by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
(sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
libc will be automatically downgraded to -fstack-protector because it
breaks rtld otherwise.
- This option is unavailable on ia64.
Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.

a. The BSD version will be built and installed unless
WITHOUT_BSD_CPIO is defined.
b. The GNU version will not be built or installed unless
WITH_GNU_CPIO is defined. If this is defined, the symlink
in /usr/bin will be to the GNU version whether the BSD
version is present or not.
When these changes are MFCed the defaults should be flipped.
2. Add a knob to disable the building of GNU grep. This will
make it easier for those that want to test the BSD version in
the ports.

parts relied on the now removed NET_NEEDS_GIANT.
Most of I4B has been disconnected from the build
since July 2007 in HEAD/RELENG_7.
This is what was removed:
- configuration in /etc/isdn
- examples
- man pages
- kernel configuration
- sys/i4b (drivers, layers, include files)
- user space tools
- i4b support from ppp
- further documentation
Discussed with: rwatson, re
default to the value of MK_KERBEROS unless set explicitly by
WITH_GSSAPI/WITHOUT_GSSAPI. (This introduces another type of
MK_* variables which itself is questionable.)
- Teach tools/build/options/makeman script that generates the
src.conf(5) manpage about the new type of MK_* variables.
- Fix broken logic in lib/Makefile.
WITHOUT_KERBEROS knob. While GSS can be used for other things
some third party software (most notably ports/x11/kdelibs3)
takes the presence of libgssapi as an indication that kerberos
is available, and attempts to link with the kerberos libs. If
they are not available, the build will fail.
Because you might want to use GSS but not kerberos, add a knob
to re-enable it if WITHOUT_KERBEROS is present.
Document the new knob, and the new behavior of WITHOUT_KERBEROS.

Problem discussed/analyzed in:
PR: ports/116484
- Add and document the KVM and KVM_SUPPORT options that
are needed for the ifmcstats(3) makefile
- Garbage collect unused variables
- Add missing inclusion of bsd.own.mk where needed

NetBSD version is a feature-to-feature re-implementation of GNU
gzip using the freely-redistributable zlib and this version is
expected to be mostly bug-to-bug compatible with the GNU
implementation.
- Because this is a piece of mature code and we want to make
changes so it is added directly rather than importing to
src/contrib.
- Connect newly added code to src/usr.bin/ and rescue/rescue
build.
- Disconnect the GNU gzip code from build for now, they will
be eventually removed completely.
- Provide two new src.conf(5) knobs, WITHOUT_BZIP2_SUPPORT and
WITHOUT_BZIP2.

to WITH_CDDL.
This option enables building code that is licensed under Sun's CDDL.
The DTrace code is licensed that way, so by default it will get built
unless the WITHOUT_CDDL option is used.
There is another build toggle, NO_CTF, which turns off execution of
ctfconvert and ctfmerge in sys.mk, but this can't be implemented as
WITH_/WITHOUT because bsd.own.mk isn't included in all Makefiles and
sys.mk is included automatically by make.
