\item XXX Introduce two new flag bits that can be set in a PyMethodDef method
descriptor, as used for the tp_methods slot of a type. These new flag
bits are both optional, and mutually exclusive. Most methods will not
use either. These flags are used to create special method types which
exist in the same namespace as normal methods without having to use
tedious construction code to insert the new special method objects in
the type's tp_dict after PyType_Ready() has been called.
If METH_CLASS is specified, the method will represent a class method
like that returned by the classmethod() built-in.
If METH_STATIC is specified, the method will represent a static method
like that returned by the staticmethod() built-in.
These flags may not be used in the PyMethodDef table for modules since
these special method types are not meaningful in that case; a
ValueError will be raised if these flags are found in that context.
\item It's now possible to define class and static methods for a C
extension type by setting either the \constant{METH_CLASS} or
\constant{METH_STATIC} flags in a method's \ctype{PyMethodDef}
structure.

\subsection{Port-Specific Changes}
XXX write this
XXX OS/2 EMX port
XXX MacOS: Weaklink most toolbox modules, improving backward
compatibility. Modules will no longer fail to load if a single routine
is missing on the curent OS version, in stead calling the missing
routine will raise an exception. Should finally fix 531398. 2.2.1
candidate. Also blacklisted some constants with definitions that
were not Python-compatible.
On MacOS, most toolbox modules have been weaklinked to improve
backward compatibility. This means that modules will no longer fail
to load if a single routine is missing on the curent OS version.
Instead calling the missing routine will raise an exception.
XXX Checked in Sean Reifschneider's RPM spec file and patches.
Sean Reifschneider contributed an updated RPM spec file that can be
found in the \file{Misc/RPM/} directory in the Python source
distribution.
