Issue #15782: Prevent compile errors of OS X Carbon modules _Fm, _Qd, and
_Qdoffs when compiling with an SDK of 10.7 or later.  The OS X APIs they
wrap have long been deprecated and have now been removed with 10.7.
These modules were already empty for 64-bit builds and have been removed
in Python 3.  (Original patch by Ronald Oussoren.)

 .. note::
 
-   These modules are deprecated and have been removed in Python 3.x.
+   Most of the OS X APIs that these modules use are deprecated or removed
+   in recent versions of OS X.  Many are not available when Python is
+   executing in 64-bit mode.  These modules have been removed in
+   Python 3.  You should avoid using them in Python 2.
