The attached patch enables shared extension
modules to build cleanly under Cygwin without
moving the static initialization of certain function
pointers (i.e., ones exported from the Python
DLL core) to a module initialization function.

Additionally, this patch fixes the modules that
have been changed in the past to accommodate
Cygwin.

Christian Tismer pointed out the high cost of the loop overhead and
function call overhead for 'c' * n where n is large.  Accordingly,
the new code only makes lg2(n) loops.

Interestingly, 'c' * 1000 * 1000 ran a bit faster with old code.  At some
point, the loop and function call overhead became cheaper than invalidating
the cache with lengthy memcpys.  But for more typical sizes of n, the new
code runs much faster and for larger values of n it runs only a bit slower.

- improved readability of rmtree; removed silly apply()

Adding try/except allows the test to pass

localtime()/gmtime() insists on delivering them, + associated doc
changes.

Redid the docs for datetimtez.astimezone().

(backport candidate?)

The range of u=random() is [0,1), so log(u) and 1/x can fail.
Fix by setting u=1-random() or by reselecting for a usable value.

Will backport.

Check whether self is NULL in mainloop.

cases, plus even tougher tests of that.  This implementation follows
the correctness proof very closely, and should also be quicker (yes,
I wrote the proof before the code, and the code proves the proof <wink>).

It was once available so that faster generators could be substituted.  Now,
that is less necessary and preferrably done via subclassing.

Also, clarified and shortened the comments for sample().

platform-specific verbiage lives.

supported version.

bsddb module build note to reflect the inclusion of bsddb3 and the demotion
of the old bsddb module.

Clarify the operation of locals().

Minor fixes to markup, spelling, parameter names, and abbreviations.

1. Annotate the shell window with last restart boundary upon restart.
2. Provide a shell menu entry and hot key (F6) to jump to the last
   restart boundary.
3. Add a new shell menu feature to restart the shell.
4. Update the help menu to add these features.
5. Update the help menu to put text in same order as the menus.
6. Correct a capitalization inconsistency on the Edit menu: Expand Word
7. Rename the "Debug" menu to be "Shell": it's doing more now.
8. Rearrange the "Shell" menu to make the StackViewer entries adjacent.
9. Add a get_geometry method to EditorWindow, which may be of use in
   making window positions persisent.
10. Make <ctrl-v> the "Classic Windows" paste key.
11. Restore decorum on the Help menu by removing "Advice".  As Guido said,
    things will never be the same.  Thanks, David!

Refactor code in PyCFunction_Call giving a modest (tiny) speed boost,
a slight improvement in semantics (now detects invalid flag combinations),
and (arguably) improved clarity (making it blindingly clear which flag
combinations are allowed).  All this comes at a cost of a few lines of
code duplication.

* Folded test for METH_KEYWORDS into the switch/case.
* Deferred testing for an empty dictionary until when and where needed.
* Make a similar deferral for filling the "size" variable.
* Inverted the dictionary test so that the common case falls though
  instead of making a jump.

the desired compromise behavior during the "problem hour" when DST ends
cheaply (but I haven't yet implemented that).

Provide .string attribute and __unicode for Tcl_Objs.
