Block objects [1] are a C-level syntactic and runtime feature. They
are similar to standard C functions, but in addition to executable
code they may also contain variable bindings to automatic (stack)
or managed (heap) memory. A block can therefore maintain a set of
state (data) that it can use to impact behavior when executed.
This port is based on Apple's GCC 5646 with some bugfixes from
Apple GCC 5666.3. It has some small differences with the support
in clang, which remains the recommended compiler.
Perhaps the most notable difference is that in GCC that __block
is not actually a keyword, but a macro. There will be workaround
for this issue in a near future. Other issues can be consulted in
the clang documentation [2]
For better compatiblity with Apple's GCC and llvm-gcc some related
fixes and features from Apple have been included. Support for the
non-standard nested functions in GCC is now off by default.
No effort was made to update the ObjC support since FreeBSD doesn't
carry ObjC in the base system, but some of the code crept in and
was more difficult to remove than to adjust.

This fixes GCC 19564:
http://gcc.gnu.org/ml/gcc-patches/2006-12/msg00868.html
http://gcc.gnu.org/ml/gcc-patches/2006-12/msg01772.html
http://gcc.gnu.org/ml/gcc-patches/2007-01/msg00545.html
The patch and its fixes are used by Google in their enhanced gcc-4.2.1
port and predates the license switch in GCC so they are still under
GPLv2.

1.2 framework for our kernel printf enhancements.
1.3 suppress prototype warnings on K&R main.
Both flag variables declared here were disconnected through the 5-current
lifetime and are retained here for backwards compatibility reasons only.
