Benjamin Peterson a72d15c97f consistently use Py_TYPE, Py_REFCNT, and correct initializer macros (#3563)
This no-op change makes 2.7 more consistent with 3.x to ease comparison and backports.

Martin Panter 646b528467 Issue #22463: Backport compiler warning fixes and workarounds
* Set but unused variable in Parser/pgen.c in non-debug builds. Patch by
  Christian Heimes.
* Unused static function in Modules/readline.c. Patch by Georg Brandl.
* main_window unused in Modules/tkappinit.c. Patch by Gregory P. Smith.
* Dead assignment in Modules/_ctypes/cfield.c. Extracted from patch by Brett
  Cannon.
* Expression result unused in PyObject_INIT macro expansions. Based on
  patches by Christian Heimes.
* Load expat_config.h and therefore pyconfig.h before C stdlib headers are
  loaded. This silences pre-processor warnings including '_POSIX_C_SOURCE
  redefined'. Extracted from patch by Christian Heimes.

Serhiy Storchaka 8d30ad7c8a Issue #24731: Fixed crash on converting objects with special methods
__str__, __trunc__, and __float__ returning instances of subclasses of
str, long, and float to subclasses of str, long, and float correspondingly.

Serhiy Storchaka 6156560e4b Issue #25678: Copy buffer objects to null-terminated strings.
Avoid buffer overreads when int(), long(), float(), and compile()
are passed buffer objects.  Similar code is removed from the
complex() constructor, where it was not reachable.

Patch backported from issue #24802 by Eryk Sun.

Mark Dickinson 31f0cfef0e Include ieeefp.h (when available) in pyport.h instead of individually in
Objects/floatobject.c and Objects/complexobject.c.  This should silence
compiler warnings about implicit declaration of the 'finite' function

Mark Dickinson bd15a06fd3 Issue #7117, continued: Change round implementation to use the correctly-rounded

Eric Smith 068f06568b Issue #5835, deprecate PyOS_ascii_formatd.
If anyone wants to clean up the documentation, feel free. It's my first documentation foray, and it's not that great.

Will port to py3k with a different strategy.

Gregory P. Smith dd96db63f6 This reverts r63675 based on the discussion in this thread:
http://mail.python.org/pipermail/python-dev/2008-June/079988.html

Python 2.6 should stick with PyString_* in its codebase.  The PyBytes_* names
in the spirit of 3.0 are available via a #define only.  See the email thread.

Christian Heimes 6f34109384 I finally got the time to update and merge Mark's and my trunk-math branch. The patch is collaborated work of Mark Dickinson and me. It was mostly done a few months ago. The patch fixes a lot of loose ends and edge cases related to operations with NaN, INF, very small values and complex math.
The patch also adds acosh, asinh, atanh, log1p and copysign to all platforms. Finally it fixes differences between platforms like different results or exceptions for edge cases. Have fun :)

Also fix the (already existing) test for this behaviour
so that it actually raises TestFailed instead of just
referencing it.
