* you can #include <sys/endian.h> instead of <machine/endian.h>,
and ditto <endian.h>  (fixes code that pulls in <sys/endian.h> first)
* those will always export the symbols that POSIX specified for
<endian.h>, including the new {be,le}{16,32,64}toh() set.  c.f.
http://austingroupbugs.net/view.php?id=162
if __BSD_VISIBLE then you also get the symbols that our <machine/endian.h>
currently exports (ntohs, NTOHS, dlg's bemtoh*, etc)
* when doing POSIX compiles (not __BSD_VISIBLE), then <netinet/in.h> and
<arpa/inet.h> will *stop* exporting the extra symbols like BYTE_ORDER
and betoh*

It's not a standard interface, so it doesn't belong in libc.
I hate duplicating the code in client programs, so do beck@, kettenis@,
schwarze@, millert@, miod@... and they agree with libutil.

as configuration files; split manpages and .pc files between libcrypto and
libssl.
No functional change, only there to make engineering easier, and libcrypto
sources are still found in libssl/src/crypto at the moment.
ok reyk@, also discussed with deraadt@ beck@ and the usual crypto suspects.

Discussion and ongoing work to fix the ports tree from many, especially

[There is a bit more cleanup possible after that, but this is considered
the current safe step]

Committing now to unbreak ports builds (gvfs fails without, which knocks
out building much of the tree.)

ok miod

headers from any subdirectory of dev/pci/drm.  If we ever add more drm(4)
drivers any headers needed by userland should end up in dev/pci/drm.
ok mpi@, miod@

Change the logic depending upon COMPILER_VERSION everywhere, to assume gcc4
is the norm and to explicitely test for gcc3 when a different behaviour
is required.
No functional change intended. Be sure to `make install' in share/mk before
attempting to do anything.

ok kettenis

of the latter.  Permits the misleading lib/libpthread/Makefile to be
removed
discussed with deraadt@

MI float.h which pulls in and defines the values that are needed from
there, and repair sys/limits.h so that it defines the values it needs
as well (depending on POSIX version, XPG version, etc).  guenther has
a more exact selection of that coming for limits.h.
this also fixes a few mistakes for the vax.
reviewed by kettenis and guenther.

- everything that has prereq will also do includes, add it late, so that
gnu stuff (the only part with prereq) happens late.
- new RUN_MAKE snippet, to be able to have the makefile magically decide
between Makefile.bsd-wrapper and Makefile.
So there's no longer any need to remember complicated rules: add it to
RDIRS if it just wants make includes, add it to PRDIRS if it wants prereq too,
and that's all.

FreeBSD's implementation via Frank Denis, with various cleanups and
tweaks by me.
ok deraadt@, guenther@; discussions and tweaks from many others
jmc@ promises to help me further with the man pages in tree

and complex math routines are complete.  OK kettenis@.

- add nearbyint, nearbyintf and nearbyintl implemented using fenv

as discussed with Theo, so that he can synch set.
