920b965865 MFp4 bz_ipv6_fast:
in_cksum.h required ip.h to be included for struct ip.  To be
  able to use some general checksum functions like in_addword()
  in a non-IPv4 context, limit the (also exported to user space)
  IPv4 specific functions to the times, when the ip.h header is
  present and IPVERSION is defined (to 4).

  We should consider more general checksum (updating) functions
  to also allow easier incremental checksum updates in the L3/4
  stack and firewalls, as well as ponder further requirements by
  certain NIC drivers needing slightly different pseudo values
  in offloading cases.  Thinking in terms of a better "library".

a5f50ef9e4 netchild's mega-patch to isolate compiler dependencies into a central
place.

This moves the dependency on GCC's and other compiler's features into
the central sys/cdefs.h file, while the individual source files can
then refer to #ifdef __COMPILER_FEATURE_FOO where they by now used to
refer to #if __GNUC__ > 3.1415 && __BARC__ <= 42.

By now, GCC and ICC (the Intel compiler) have been actively tested on
IA32 platforms by netchild.  Extension to other compilers is supposed
to be possible, of course.

1ebcad5720 This is the first snapshot of the FreeBSD/ia64 kernel. This kernel will
not work on any real hardware (or fully work on any simulator). Much more
needs to happen before this is actually functional but its nice to see
the FreeBSD copyright message appear in the ia64 simulator.
