A change from Duncan Booth, to deal with changes in the way pgen gets
built.  Note that graminit.[ch] aren't normally built on Windows (they're
obtained from CVS).

operate on the module dictionary directly.  This prevents spurious
depreciation warnings from being raised if a submodule name shadows
a builtin name.

SF bug [ 751276 ] cPickle doesn't raise error, pickle does (recursiondepth)

Most of the calls to PyErr_Clear() were intended to catch & clear an
attribute error and try something different.  Guard all those cases
with a PyErr_ExceptionMatches() and fail if some other error
occurred.  The other error is likely a bug in the user code.

This is basically the C equivalent of changing "except:" to
"except AttributeError:"

build directory is found to exist we don't clean it up. We also
use configure -C. All this lets us keep build directories, which
graeatly speeds up the process of debugging installers.

besides plain tuples.

tell Windows Truth too.

Bugfix candidate.

Add explicit text for where an obindex call for generators was since obindex does not cause output of its argument.

Return None to signal that the module the object was defined in was not found when object has no __name__ attr but is needed to figure out location of object.

unique boundary strings within a program run are guaranteed.  On Windows,
duplicates were pretty likely, due to the coarse granularity of time.time.
Toned down the absurdly optimistic claims in the docstring.

Bugfix candidate.

Also install the start script from Tools/script/idle.  (This may
change again.)

Tools/idle, in both source and destination.  (There are still problems
when running the IDLE icon, but they don't seem to have to do with the
installer.)

This was reported in the IDLEFORK bug tracker as #754971.

Convert characters from the locale's encoding on output

by providing other modules access to globals set up in PyShell.main()

Define True and False (if necessary) so this module can be copied as-is
to other projects (eg. Optik, Docutils) that don't depend on Python 2.3.

Remove deprecated tempfile usage

Fixes #754447.
