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.
SF patch #1630975: Fix crash when replacing sys.stdout in sitecustomize
When running the interpreter in an environment that would cause it to set
stdout/stderr/stdin's encoding, having a sitecustomize that would replace
them with something other than PyFile objects would crash the interpreter.
Fix it by simply ignoring the encoding-setting for non-files.
This could do with a test, but I can think of no maintainable and portable
way to test this bug, short of adding a sitecustomize.py to the buildsystem
and have it always run with it (hmmm....)
the need for the out-of-tree universal binary support that was used to build
the 2.4.3 installer.
Missing here relative to that tree are some changes to IDLE, IMHO those patches
aren't appropriate for the 2.4 branch and users are better of using 2.5's IDLE.
this code is only used if WITHOUT_COMPLEX is *not* defined, which is the
common case for Python builds.]
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.

v2 can be NULL if exception2 is NULL. I don't think that condition can happen,
but I'm not sure it can't either. Now the code will protect against either
being NULL.
cpathname could be NULL if it was longer than MAXPATHLEN. Don't try
to write the .pyc to NULL.
Check results of PyList_GetItem() and PyModule_GetDict() are not NULL.

* 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.
Handle more mem alloc issues found with failmalloc
[The other half of this patch affected Python/symtable.c, and wasn't
relevant for the 2.4 branch. --amk]
