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.

Last try for tweaking the max stack depth. 5000 was the original value,
...
4000 didn't work either. 1000 does work on Windows. If 2000 works,
that will hopefully be a reasonable balance.

Set the depth to something very small to try to determine if the

crashes on Windows are really due to the stack size or possibly
some other problem.

Reduce the max stack depth to see if this fixes the segfaults on

Windows and some other boxes. If this is successful, this rev should
be backported. I'm not sure how close to the limit we should push this.

Forward-port of r52136,52138: a review of overflow-detecting code.
...
* 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...

This code is actually not used unless WITHOUT_COMPLEX is defined.
...
However, there was no error checking that PyFloat_FromDouble returned
a valid pointer. I believe this change is correct as it seemed
to follow other code in the area.

the extra initializations will matter one way or another.)
