- add awarning about reconfiguring after Slackware96 fix
- add reference to Jim F's ExtensionClass module

not exist.  All 8 uses of tkinter are replaced with _tkinter.  Still
create a variable tkinter though, because that is used by other
modules importing Tkinter (e.g. tkinter.createfilehandler()).

Also added a comment to the 'import _tkinter' line saying that if this
fails, Python is not configured correctly.

New symbol WANT_SIGFPE_HANDLER.

Two new modules fpectl and fpetest.
Surround various and sundry f.p. operations with PyFPE_*_PROTECT macros.

New file pyfpe.c and exception FloatingPointError.
Surround some f.p. operations with PyFPE macro brackets.

Surround various f.p. operations with  PyFPE_{START,END}_PROTECT macros.

New file pyfpe.h, new exception FloatingPointError.

lint happy.

even if it isn't.  Changes:

- set the global flag Py_InteractiveFlag when -i is given
- call Py_FdIsInteractive() instead of isatty()
- make stdin unbuffered, too, when using -u
- make stdin and stdout line buffered, when stdin is interactive and not -u

Note that setting the environment variable PYTHONINSPECT does not have
these extra effects of -i.  (Should it?)

Unlike Lee's changes, I don't set change the prompt to go to stderr
when -i is given.

Py_FdIsInteractive().  The flag is supposed to be set by the -i
command line option.  The function is supposed to be called instead of
isatty().  This is used for Lee Busby's wish #1, to have an option
that pretends stdin is interactive even when it really isn't.

Run the loop up to and including 8k.

by the frameobject dealloc when it is time for the locals to go.  When
there's still a traceback object referencing this stack frame, we
don't want the local variables to disappear yet.

(Hmm...  Shouldn't they be copied to the f_locals dictionary?)

and if there's a pointer to an interned version of the string, use its
hash and store its hash in this object, rather than recomputing it.

from ceval.c).

Wrapped a long line.

Removed select_adjust -- Tk no longer supports this.

add(): better handling of overflow (substitute maxval instead of
throwing away higher order bits).

ratecv(): some bugfixes, Sjoerd says.

by all true Tkinter widgets.  (Not that I *like* this module -- it
stinks, but until I have something better, I can't nuke it.)

I'll clean that up later.  Also corrected a mistake introduced by the
previous reformatting: an 'else' belonging to a 'for' was accidentally
reindented to belong to the 'if' inside the 'for'.  Note that the
module uses inconsistent indentation -- most code is indented with 8
spaces, but some of the reformatted code uses 4 spaces.  I'll fix this
later in the promised cleanup pass.
