Bug #1572832: fix a bug in ISO-2022 codecs which may cause segfault
when encoding non-BMP unicode characters.  (Submitted by Ray Chason)

Backport the .sln and .vcproj files for PCBuild8 from the python trunk to the 2.5 maintainance branch.  This fixes build problems with visual studio 2005, and cleans up profile guided optimization.

Cause a PyObject_Malloc() failure to trigger a MemoryError, and then
add 'if (PyErr_Occurred())' checks to various places so that NULL is
returned properly.

* unified the way intobject, longobject and mystrtoul handle
  values around -sys.maxint-1.

* in general, trying to entierely avoid overflows in any computation
  involving signed ints or longs is extremely involved.  Fixed a few
  simple cases where a compiler might be too clever (but that's all
  guesswork).

* more overflow checks against bad data in marshal.c.

* 2.5 specific: fixed a number of places that were still confusing int
  and Py_ssize_t.  Some of them could potentially have caused
  "real-world" breakage.

* list.pop(x): fixing overflow issues on x was messy.  I just reverted
  to PyArg_ParseTuple("n"), which does the right thing.  (An obscure
  test was trying to give a Decimal to list.pop()... doesn't make
  sense any more IMHO)

* trying to write a few tests...

(unsigned long vs. unsigned int).

Since this paragraph is about exception's message attribute(2.5 feature),
I will not backport to 2.4 branch.

Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).

These tests should be improved.  Hopefully this fixes variations when
flipping back and forth between fpdef and fplist.

Fix %zd string formatting on Mac OS X so it prints negative numbers.

In addition to testing positive numbers, verify negative numbers work in configure.
In order to avoid compiler warnings on OS X 10.4, also change the order of the check
for the format character to use (PY_FORMAT_SIZE_T) in the sprintf format
for Py_ssize_t.  This patch changes PY_FORMAT_SIZE_T from "" to "l" if it wasn't
defined at configure time.  Need to verify the buildbot results.

being raised when print_exc() was called without an exception set.
In version 2.4, this printed "None", restored that behavior.

* regression bug, count_next was coercing a Py_ssize_t to an unsigned Py_size_t
  which breaks negative counts
* added test for negative numbers

(damn, it's nice to see the line
  #define PY_VERSION              "2.5"
in patchlevel.h)
