As of Xcode 7, SDKs for Apple platforms now include textual-format stub
libraries whose file names have a .tbd extension rather than the
standard OS X .dylib extension.  The Apple compiler tool chain handles
these stub libraries transparently and the installed system shared libraries
are still .dylibs.  However, the new stub libraries cause problems for
third-party programs that support building with Apple SDKs and make
build-time decisions based on the presence or paths of system-supplied
shared libraries in the SDK.  In particular, building Python itself with
an SDK fails to find system-supplied libraries during setup.py's build of
standard library extension modules.  The solution is to have
find_library_file() in Distutils search for .tbd files, along with
the existing types (.a, .so, and .dylib).  Patch by Tim Smith.

    In particular, fix extension module build failures when trying to use
    32-bit-only installer Pythons on systems with Xcode 4 (currently
    OS X 10.8, 10.7, and optionally 10.6).
    * Backport 3.3.0 fixes to 3.2 branch (for release in 3.2.4)
    * Since Xcode 4 removes ppc support, extension module builds now
      check for ppc compiler support and by default remove ppc and
      ppc64 archs when they are not available.
    * Extension module builds now revert to using system installed
      headers and libs (/usr and /System/Library) if the SDK used
      to build the interpreter is not installed or has moved.
    * Try to avoid building extension modules with deprecated
      and problematic Apple llvm-gcc compiler.  If original compiler
      is not available, use clang instead by default.

tailoring for universal builds by factoring out common OS X-specific
customizations from sysconfig, distutils.sysconfig, distutils.util,
and distutils.unixccompiler into a new module _osx_support that can
eventually also be used by packaging.

- fix test_distutils and test_sysconfig test failures by
  aligning sysconfig and distutils.sysconfig tailoring of
  configure variables (as in 2.7)

- Try to avoid building Python or extension modules with problematic
  llvm-gcc compiler.
- Since Xcode 4 removes ppc support, extension module builds now
  check for ppc compiler support and automatically remove ppc and
  ppc64 archs when not available.
- Since Xcode 4 no longer install SDKs in default locations,
  extension module builds now revert to using installed headers
  and libs if the SDK used to build the interpreter is not
  available.
- Update ./configure to use better defaults for universal builds;
  in particular, --enable-universalsdk=yes uses the Xcode default
  SDK and --with-universal-archs now defaults to "intel" if ppc
  not available.

Fix closes Issue11439 Remove the SVN keywords from the code as it is no longer applicable in hg. Patch Contributed by Neil Muller.

reverted distutils its 3.1 state. All new work is now happening in disutils2, and distutils is now feature-frozen.

    Two small fixes for the support for SDKs on MacOSX:

    1) The code that checks if an path should be located in the SDK
       explicitly excludes /usr/local. This fixes issue9046

    2) The SDK variant for filtering "db_dirs_to_check" in setup.py
       was not doing anything because of a missing assignment.

  MacOS X: Enable 4-way universal builds

  This patch adds a new configure argument on OSX:
          --with-universal-archs=[32-bit|64-bit|all]

  When used with the --enable-universalsdk option this controls which
  CPU architectures are includes in the framework. The default is 32-bit,
  meaning i386 and ppc. The most useful alternative is 'all', which includes
  all 4 CPU architectures supported by MacOS X (i386, ppc, x86_64 and ppc64).

  This includes limited support for the Carbon bindings in 64-bit mode as well,
  limited because (a) I haven't done extensive testing and (b) a large portion
  of the Carbon API's aren't available in 64-bit mode anyway.

  I've also duplicated a feature of Apple's build of python: setting the
  environment variable 'ARCHFLAGS' controls the '-arch' flags used for building
  extensions using distutils.
