I've made clang the default on x86 systems. There will probably be a
few bumps as we work out the last kinks including a ABI issue for i386
system libraries, but the transition is expected to be fairly smooth for
most users.
Please report problems on freebsd-current or freebsd-toolchain.

+20121105:
+ On i386 and amd64 systems WITH_CLANG_IS_CC is now the default.
+ This means that the world and kernel will be compiled with clang
+ and that clang will be installed as /usr/bin/cc, /usr/bin/c++,
+ and /usr/bin/cpp. To disable this behavior and revert to building
+ with gcc, compiler with WITHOUT_CLANG_IS_CC.

The IPFIREWALL_FORWARD kernel option has been removed. Its
functionality now turned on by default.
