154b7ad07e Issue #1530559: When packing a non-integer with any integer conversion 
code using struct.pack, attempt to convert to an integer first using
the argument's __int__ method (if present).  Also raise a
DeprecationWarning for any such usage of __int__.

This fixes a regression from 2.6, where some (but not all) integer
conversion codes already used __int__.

1c0c78c61f Fix incorrect stacklevel for DeprecationWarnings originating from the struct module. 
Also clean up related tests in test_struct.
The stacklevel fix should be backported to 2.6 once that branch is unfrozen.

7937d939b1 Fix nearly all compilation warnings under Apple gcc-4.0. Tested with OPT="-g 
-Wall -Wstrict-prototypes -Werror" in both --with-pydebug mode and --without.
There's still a batch of non-prototype warnings in Xlib.h that I don't know how
to fix.

9d53457e59 Merge in release25-maint r60793: 
Added checks for integer overflows, contributed by Google. Some are
 only available if asserts are left in the code, in cases where they
 can't be triggered from Python code.

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.

f3c0559b5e Issue 1872: Changed the struct module typecode from 't' to '?', for

588ff93f13 Crashers of the day: Py_CLEAR must be used when there is a chance that the 
function can be called recursively.
This was discussed in issue1020188.

In python codebase, all occurrences of Py_[X]DECREF(xxx->yyy) are suspect,
except when they appear in tp_new or tp_dealloc functions, or when
the member cannot be of a user-defined class.
Note that tp_init is not safe.

I do have a (crashing) example for every changed line.
Is it worth adding them to the test suite?

Example:

class SpecialStr(str):
    def __del__(self):
        s.close()

import cStringIO
s = cStringIO.StringIO(SpecialStr("text"))
s.close() # Segfault
