backwards compatibility.  When using the class of the first base as
the metaclass, use its __class__ attribute in preference over its
ob_type slot.  This ensures that we can still use classic classes as
metaclasse, as shown in the original "Metaclasses" essay.  This also
makes all the examples in Demo/metaclasses/ work again (maybe these
should be turned into a test suite?).

Inhibited complex unary plus optimization when applied to a complex subtype.
Added PyComplex_CheckExact macro.  Some comments and minor code fiddling.

errors occur.)

with the same value instead.  This ensures that a string (or string
subclass) object's ob_sinterned pointer is always a str (or NULL), and
that the dict of interned strings only has strs as keys.

+ These were leaving the hash fields at 0, which all string and unicode
  routines believe is a legitimate hash code.  As a result, hash() applied
  to str and unicode subclass instances always returned 0, which in turn
  confused dict operations, etc.
+ Changed local names "new"; no point to antagonizing C++ compilers.

ljust, rjust, center and strip.  I don't know how to be sure they've all
been caught.

Question:  Should we complain if someone tries to intern an instance of
a string subclass?  I hate to slow any code on those paths.

with value 12345.

that will detect an __main__.py or __rawmain__.py in the application bundle.
This file is then exectued as the main script. We now have applets in
MachO Python!!!

The difference between __main__ and __rawmain__ is that the former gets a
complete simulated argv (so you can drop files on the applet and the script
sees them in sys.argv) while the latter skips the argv simulation and the
<option>key dialog. This keeps the AppleEvent that started the app intact,
as well as the funny "-psn_xxxx" argv[1] argument, so the script can do
with these what it wants.

- Allow any file to be dropped on the interpreter (for file args).
