Pedro F. Giffuni 81e5b01765 gcc: Bring updates from Google's enhanced gcc-4.2.1.
Google released and enhanced version of gcc-4.2.1 plus their local
patches for Android[1].

The patches are owned by Google and the license hasn't been changed
from  the original GPLv2. We are only bringing a subset of the
available patches that may be helpful in FreeBSD. Changes specific
to android are not included.

From the README.google file[1].

README

file: libstdc++-v3/README

New users may wish to point their web browsers to the file
documentation.html in the 'docs/html' subdirectory.  It contains brief
building instructions and notes on how to configure the library in
interesting ways.

Instructions for configuring and building appear in
docs/html/install.html.

This directory contains the files needed to create an ISO Standard C++
Library.

It has subdirectories:

  docs
    Files in HTML and text format that document usage, quirks of the
    implementation, and contributor checklists.

  include
    All header files for the C++ library are within this directory,
    modulo specific runtime-related files that are in the libsupc++
    directory.

    include/std
      Files meant to be found by #include <name> directives in
      standard-conforming user programs.  

    include/c
      Headers intended to directly include standard C headers. 
      [NB: this can be enabled via --enable-cheaders=c]

    include/c_std
      Headers intended to include standard C headers, and put select
      names into the std:: namespace.
      [NB: this is the default, and is the same as --enable-cheaders=c_std]

    include/bits
      Files included by standard headers and by other files in
      the bits directory. 

    include/backward
      Headers provided for backward compatibility, such as <iostream.h>.
      They are not used in this library.

    include/ext
      Headers that define extensions to the standard library.  No
      standard header refers to any of them.

  scripts
    Scripts that are used during the configure, build, make, or test
    process.

  src
    Files that are used in constructing the library, but are not
    installed.

  testsuites/[backward, demangle, ext, performance, thread, 17_* to 27_*]
    Test programs are here, and may be used to begin to exercise the 
    library.  Support for "make check" and "make check-install" is
    complete, and runs through all the subdirectories here when this
    command is issued from the build directory.  Please note that
    "make check" requires DejaGNU 1.4 or later to be installed.  Please
    note that "make check-script" calls the script mkcheck, which
    requires bash, and which may need the paths to bash adjusted to
    work properly, as /bin/bash is assumed.

Other subdirectories contain variant versions of certain files
that are meant to be copied or linked by the configure script.
Currently these are:

  config/abi
  config/cpu
  config/io
  config/locale
  config/os

In addition, two subdirectories are convenience libraries:

  libmath
    Support routines needed for C++ math. Only needed if the
    underlying "C" implementation is non-existent, in particular
    required or optimal long double, long long, and C99 functionality.

  libsupc++
    Contains the runtime library for C++, including exception
    handling and memory allocation and deallocation, RTTI, terminate
    handlers, etc.

Note that glibc also has a bits/ subdirectory.  We will either
need to be careful not to collide with names in its bits/
directory; or rename bits to (e.g.) cppbits/.

In files throughout the system, lines marked with an "XXX" indicate
a bug or incompletely-implemented feature.  Lines marked "XXX MT"
indicate a place that may require attention for multi-thread safety.
