installer package from the OS X Makefile for Python 3.  It has
never worked on Python 3 and is not needed there as pre-10.3.9
installs are no longer supported.

Builds are not yet fully supported on Python 3 as some parts
of the build process (like the documentation build chain)
are still dependent on Python 2.

Issue #4489: Rename the feature marker for the symlink resistant rmtree and store it as a function attribute

    * update README

(This was not done in the previous commit because Mercurial would have
shown it as a modified file instead of a moved file.)

Distutils2 will live on on PyPI and be included in the stdlib when it
is ready.  See discussion starting at
http://mail.python.org/pipermail/python-dev/2012-June/120430.html

#11113: add a new "html5" dictionary containing the named character references defined by the HTML5 standard and the equivalent Unicode character(s) to the html.entities module.

Patch written by Georg Brandl.  (I'm really looking forward to George
getting commit privileges so I don't have to keep doing checkins on his
behalf.)

(this could reveal test failures!)

- 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.

Also add an explicit test for safe implementation usage on supported platforms.

As a side effect, this commit adds a module-level attribute 'rmtree_is_safe'
which offers introspection whether the current rmtree implementation is safe
against symlink attacks.

Issue #15142: Fix reference leak when deallocating instances of types created using PyType_FromSpec().

Issue #12965: Clean up C-API docs for PyLong_AsLongLong(AndOverflow); clarify that __int__ will be called for non-PyLongs

It is used automatically on platforms supporting the necessary os.openat() and
os.unlinkat() functions. Main code by Martin von Löwis.
