It's quite arguably a bugfix, since datetime.h in 2.3.4 exposes things
that can't possibly be used outside of datetimemodule.c (the datetime
type objects are referenced in the header, but not exported in a
usable way).  Anthony Tuininga's patch to *finish* (not really add)
the datetime C API is a low-risk change regardless:  it doesn't change
any existing functionality, it just finishes the job of exposing it to
C coders, and adds some new macros for convenience.

Now if some platform header file has macros with names like

    PyDateTime_FromTimestamp
or
    PyDelta_FromDSU

then adding these macros to datetime.h could cause new problems.  But
platform header files don't have macros with names like those (if they
did, we would have bumped into it while developing 2.4).
