While beeing here also correct the following:
- list missing macros in the header
- document MALLOC_DEFINE and MALLOC_DECLARE in the SYNOPSIS section
- document additional include requirements for MALLOC_DEFINE
- M_NOWAIT is not 0 anymore
- remove rotted diagnostic messages
This is an optional feature, disabled by default.
This will be useful to people testing the various POSIX threading
libraries under -CURRENT but can easily serve other needs.

FreeBSD. This method attempts to centralize all the necessary hacks
or work arounds in one of two places in the tree (src/Makefile.inc1
and src/tools/build). We build a small compatibility library
(libbuild.a) as well as selectively installing necessary include
files. We then include this directory when building host binaries.
This removes all the past release compatibilty hacks from various
places in the tree. We still build on tip of stable and current. I
will work with those that want to support more, although I anticipate
it will just work.
Many thanks to ru@, obrien@ and jhb@ for providing valuable input at
various stage of implementation, as well as for working together to
positively effect a change for the better.

This fulfills the host requirements for userland support by
way of the setsockopt() IP_EVIL_INTENT message.
There are three sysctl tunables provided to govern system behavior.
net.inet.ip.rfc3514:
Enables support for rfc3514. As this is an
Informational RFC and support is not yet widespread
this option is disabled by default.
net.inet.ip.hear_no_evil
If set the host will discard all received evil packets.
net.inet.ip.speak_no_evil
If set the host will discard all transmitted evil packets.
The IP statistics counter 'ips_evil' (available via 'netstat') provides
information on the number of 'evil' packets recieved.
For reference, the '-E' option to 'ping' has been provided to demonstrate
and test the implementation.
glibc which is externally maintained, so GCC ships with these
warnings turned off by default. This is also consistent with
the src/contrib/gcc/c-lex.c,v 1.2 change.
pointed this out a while ago, and I'm just now getting back to it. It
obsoletes one of ru's changes, but since oldcard.4 is so much better,
that doesn't matter.
