b42a6953a1 Pull in r174303 from upstream gcc trunk (by Jason Merrill):
PR c++/48211
  * name-lookup.h (cp_class_binding): Make base a pointer.
  * name-lookup.c (new_class_binding): Adjust.
  (poplevel_class): Adjust.

This fixes a potential segfault when compiling gold, a part of the
devel/binutils port, with gcc.  See also the upstream bug report:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=48211

Thanks to Jason Merrill, Tom Callaway and Red Hat legal for approving
the use of this patch under the GNU GPL, version 2 or later.

321c39ba84 gcc: Add support for -Wmissing-prototypes in C++
Support for warnings about missing prototypes in C++ was added by Apple
GCC (Radar 6261539).  Most of the code crept into r260311 so it felt
natural to make use of it.

3cb44b3f65 gcc: Drop useless objc change from r260311.
Among some of the objc changes from Apple that crept into r260311,
Radar 5355344 is incomplete and is not used since we don't carry
ObjC in the base system.

The dead code seems to have caused issues in some Tinderboxes so
get rid of it altogether.

ab07951c0c gcc: backport some fixes from llvm-gcc
llvm-gcc backported some patches from gcc trunk:

http://gcc.gnu.org/ml/gcc-cvs/2007-05/msg00662.html
http://gcc.gnu.org/ml/gcc-cvs/2007-07/msg00019.html
http://gcc.gnu.org/ml/gcc-cvs/2007-08/msg00240.html
http://gcc.gnu.org/ml/gcc-cvs/2007-08/msg00493.html

The first two were always GPL2. The last two were
added after the GPL3 transition, but were written
by aaw@google.com and Rafael Espíndola got permission
to relicense them under the GPL2 for inclusion in
llvm-gcc.

This fixes GCC-PR c++/31749

5bfc7db451 gcc: Add support for Apple's Block extension
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.

d096f2f5a8 Revert r260073; small diff reduction wrt gcc43 and Apple GCC.
Unfortunately this causes ICE on powerpc and sparc64.

Reducing these differences against upstream is not important
anymore so hopefully I have finished breaking the compiler
occasionally.

2d278bb89e gcc: Add support for label attributes and "unavailable" attribute.
Apple GCC has extensions to support for both label attributes and
an "unavailable" attribute. These are critical for objc but are
also useful in regular C/C++.

Apparently at least the label attributes might have found their way to
upstream GCC but the code doesn't seem available on the GPLv2 tree so
we are taking the code directly from Apple. To make this clearer we
are preserving the annoying "APPLE LOCAL" tags and the ChangeLogs
when they are available.
