PyRun_FileEx(). These are the same as their non-Ex counterparts but
have an extra argument, a flag telling them to close the file when
done.
Then this is used by Py_Main() and execfile() to close the file after
it is parsed but before it is executed.
Adding APIs seems strange given the feature freeze but it's the only
way I see to close the bug report without incompatible changes.

scope. Previously, s_buffer[] was defined inside the
PyUnicode_Check() scope, but referred to in the outer scope via
assignment to s. This quiets an Insure portability warning.
accepted by the BDFL.
builtin_zip(): New function to implement the zip() function described
in the above proposal.
zip_doc[]: Docstring for zip().
builtin_methods[]: added entry for zip()
This adds support for instance to the constructor (instances
have to define __str__ and can return Unicode objects via that
hook; string return values are decoded into Unicode using the
current default encoding).
Various small fixes to the builtin module to ensure no buffer
overflows.
- chunk #1:
Proper casting to ensure no truncation, and hence no surprises, in the
comparison.
- chunk #2:
The id() function guarantees a unique return value for different
objects. It does this by returning the pointer to the object. By
returning a PyInt, on Win64 (sizeof(long) < sizeof(void*)) the pointer
is truncated and the guarantee may be proven false. The appropriate
return function is PyLong_FromVoidPtr, this returns a PyLong if that
is necessary to return the pointer without truncation.
[GvR: note that this means that id() can now return a long on Win32
platforms. This *might* break some code...]
- chunk #3:
Ensure no overflow in raw_input(). Granted the user would have to pass
in >2GB of data but it *is* a possible buffer overflow condition.
module and into _exceptions.c. This includes all the PyExc_* globals,
the bltin_exc table, init_class_exc(), fini_instances(),
finierrors().
Renamed _PyBuiltin_Init_1() to _PyBuiltin_Init() since the two phase
initializations are necessary any more.
Removed as obsolete _PyBuiltin_Init_2(), _PyBuiltin_Fini_1() and
_PyBuiltin_Fini_2().

For documentation read the comments in mymalloc.h and objimpl.h.
(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode. I'm also holding back on his
change to main.c, which seems unnecessary to me.)
- When 'import exceptions' fails, don't suggest to use -v to print the traceback;
this doesn't actually work.
- Remove comment about fallback to string exceptions.
- Remove a PyErr_Occurred() check after all is said and done that can
never trigger.
- Remove static function newstdexception() which is no longer called.
are no longer supported (i.e. -X option is removed).
_PyBuiltin_Init_1(): Don't call initerrors(). This does mean that it
is possible to raise an ImportError before that exception has been
initialized, say because exceptions.py can't be found, or contains
bogosity. See changes to errors.c for how this is handled.
_PyBuiltin_Init_2(): Don't test Py_UseClassExceptionsFlag, just go
ahead and initialize the class-based standard exceptions. If this
fails, we throw a Py_FatalError.
