Needed to init ret since it was Py_XDECREF()d on error.
All regressions pass in debug build for me.

PySequence_Fast needs to do anything siginificant.

[ 633870 ] allow any seq assignment to a list slice

plus a very silly little test case of my own.

* setup.py
  (PyBuildExt.detect_modules): Included bz2 module detection.

* Modules/bz2module.c
* Lib/test/test_bz2.py
* Doc/lib/libbz2.tex
  Included files implementing, testing, and documenting bz2 module.

* Doc/Makefile.deps
* Doc/lib/lib.tex
  Include references to libbz2.tex.

* Misc/NEWS
  (Library): Mention distutils' c++ linkage patch, and new bz2 module.

[#413582] g++ must be called for c++ extensions
[#454030] distutils cannot link C++ code with GCC

topdir = "Lib/distutils"

* bcppcompiler.py
  (BCPPCompiler.create_static_lib): Fixed prototype, removing extra_preargs
  and extra_postargs parameters. Included target_lang parameter.
  (BCPPCompiler.link): Included target_lang parameter.

* msvccompiler.py
  (MSVCCompiler.create_static_lib): Fixed prototype, removing extra_preargs
  and extra_postargs parameters. Included target_lang parameter.
  (MSVCCompiler.link): Included target_lang parameter.

* ccompiler.py
  (CCompiler): New language_map and language_order attributes, used by
  CCompiler.detect_language().

  (CCompiler.detect_language): New method, will return the language of
  a given source, or list of sources. Individual source language is
  detected using the language_map dict. When mixed sources are used,
  language_order will stablish the language precedence.

  (CCompiler.create_static_lib, CCompiler.link, CCompiler.link_executable,
   CCompiler.link_shared_object, CCompiler.link_shared_lib):
  Inlcuded target_lang parameter.

* cygwinccompiler.py
  (CygwinCCompiler.link): Included target_lang parameter.

* emxccompiler.py
  (EMXCCompiler.link): Included target_lang parameter.

* mwerkscompiler.py
  (MWerksCompiler.link): Included target_lang parameter.

* extension.py
  (Extension.__init__): New 'language' parameter/attribute, initialized
  to None by default. If provided will overlap the automatic detection
  made by CCompiler.detect_language(), in build_ext command.

* sysconfig.py
  (customize_compiler): Check Makefile for CXX option, and also the
  environment variable CXX. Use the resulting value in the 'compiler_cxx'
  parameter of compiler.set_executables().

* unixccompiler.py
  (UnixCCompiler): Included 'compiler_cxx' in executables dict, defaulting
  to 'cc'.
  (UnixCCompiler.create_static_lib): Included target_lang parameter.
  (UnixCCompiler.link): Included target_lang parameter, and made
  linker command use compiler_cxx, if target_lang is 'c++'.

* command/build_ext.py
  (build_ext.build_extension): Pass new ext.language attribute
  to compiler.link_shared_object()'s target_lang parameter. If
  ext.language is not provided, detect language using
  compiler.detect_language(sources) instead.

* command/config.py
  (config._link): Pass already available lang parameter as target_lang
  parameter of compiler.link_executable().

	/* this is harder to get right than you might think */

angered some God somewhere.  After noticing

    >>> range(5000000)[slice(96360, None, 439)]
    []

I found that my cute test for the slice being empty failed due to
overflow.  Fixed, and added simple test (not the above!).

install-script on the command line.

Recreated after recompilation of wininst.exe.

_locale.getdefaultlocale.  Guessing a leading underscore was intended,
but don't really understood this stuff (locale looks like Spanish for
the opposite of global to me <wink>).

Prevent the lengths passed to PyString_FromStringAndSize()
from being negative in some cases.

Correct source of *strip() changes
Small rewrites.

customize_compiler() now looks at various environment variables and uses
   their values to override the configured C compiler/preprocessor/linker
   binary and flags.

Fixed the signed/unsigned confusions when dealing with files >= 2GB.
4GB is still a hard limitation of the gzip file format, though.

Testing this was a bitch on Win98SE due to frequent system freezes.  It
didn't freeze while running gzip, it kept freezing while trying to *create*
a > 2GB test file!  This wasn't Python's doing.  I don't know of a
reasonable way to test this functionality in regrtest.py, so I'm not
checking in a test case (a test case would necessarily require creating
a 2GB+ file first, using gzip to zip it, using gzip to unzip it again,
and then compare before-and-after; so >4GB free space would be required,
and a loooong time; I did all this "by hand" once).

Bugfix candidate, I guess.

\@makefntext than \@footnotetext, so we'll do that instead.

   when output is redirected to a file, compiler error messages show
   up before Distutils prints the command being invoked.

   whether the Distutils being used supports a particularly capability.

   (This idea was originally suggested by Juergen Hermann as a method
    on the Distribution class.  I think it makes more sense as a
    function in core.py, and that's what this patch implements.)

The @euro part is backported to 2.2.3.

Try to write to TESTFN, if that fails, try TESTFN in /tmp
If that fails, print a warning and go on.
Will backport.

Will backport.

Redo setting the selection and setting the beacon to deal better
with rows or columns -- these are now expressed by range (1, sys.maxint).

Joseph Winston recommends removing DYNAMIC_PATH, since it can
cause some dynamic libraries to not load on HP-UX 11.

Cast param to isalnum() to int.

On HPUX, Solaris, Tru64 (Dec UNIX), and IRIX (I think),
O_NONBLOCK is the POSIX version of non-blocking I/O
which is what we want.

On Linux and FreeBSD (at least), O_NONBLOCK and O_NDELAY are the same.
So this change should have no negative effect on those platforms.

Tested on Linux, Solaris, HPUX.

Thanks to Anders Qvist for diagnosing this problem.
