In a few places, PY_FORMAT_SIZE_T was incorrectly used with
PyString_FromFormat or PyErr_Format to display size_t values. The macro
PY_FORMAT_SIZE_T is designed to select the correct format for the OS
``printf`` function, whereas PyString_FromFormat has an independent
implementation and uses "%zd" on all platforms for size_t values. This makes
a difference on win64, where ``printf`` needs "%Id" to display 64bit values.

_weakref.ref(Exception).__init__() gave invalid return value on error.

long() applied to a float object now always return a long object; previously
an int would be returned for small values. the __long__ method is allowed to
return either an int or a long, but the behaviour of float objects should
not change to respect backward compatibility.

friends, which occurred when the argument for "s*" was correctly parsed but
parsing of subsequent arguments failed.

.. section: Core and Builtins

speed up isinstance() and issubclass() by 50-70%, so as to match Python 2.5
speed despite the __instancecheck__ / __subclasscheck__ mechanism. In the
process, fix a bug where isinstance() and issubclass(), when given a tuple
of classes as second argument, were looking up __instancecheck__ /
__subclasscheck__ on the tuple rather than on each type object.
