Also grandly renamed.

Here's the new interface:

When WITH_READLINE is defined, two functions are defined:

  - PyOS_GnuReadline (what used to be my_readline() with WITH_READLINE)
  - PyOS_ReadlineInit (for Dave Ascher)

Always, these functions are defined:

  - PyOS_StdioReadline (what used to be my_readline() without WITH_READLINE)
  - PyOS_Readline (the interface used by tokenizer.c and [raw_]input().

There's a global function pointer PyOS_ReadlineFunctionPointer,
initialized to NULL.  When PyOS_Readline finds this to be NULL, it
sets it to either PyOS_GnuReadline or PyOS_StdioReadline depending on
which one makes more sense (i.e. it uses GNU only if it is defined
*and* stdin is indeed a tty device).

An embedding program that has its own wishes can set the function
pointer to a function of its own design.  It should take a char*
prompt argument (which may be NULL) and return a string *ending in a
\n character* -- or "" for EOF or NULL for a user interrupt.

string as the key to the cache.  This means that changing the syntax
will return the correct compiled pattern.

clear_cache(): New function.

unlikely to find a python binary, as /usr/local/bin is usually not on
the default search path.

works unless you don't have putenv.

- 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?)
