interning.  I modified Oren's patch significantly, but the basic idea
and most of the implementation is unchanged.  Interned strings created
with PyString_InternInPlace() are now mortal, and you must keep a
reference to the resulting string around; use the new function
PyString_InternImmortal() to create immortal interned strings.

in LOAD_GLOBAL.  Besides saving a C function call, it saves checks
whether f_globals and f_builtins are dicts, and extracting and testing
the string object's hash code is done only once.  We bail out of the
inlining if the name is not exactly a string, or when its hash is -1;
because of interning, neither should ever happen.  I believe interning
guarantees that the hash code is set, and I believe that the 'names'
tuple of a code object always contains interned strings, but I'm not
assuming that -- I'm simply testing hash != -1.

On my home machine, this makes a pystone variant with new-style
classes and slots run at the same speed as classic pystone!  (With
new-style classes but without slots, it is still a lot slower.)

comments everywhere that bugged me: /* Foo is inlined */ instead of
/* Inline Foo */.  Somehow the "is inlined" phrase always confused me
for half a second (thinking, "No it isn't" until I added the missing
"here").  The new phrase is hopefully unambiguous.

Should save 4% on slot lookups.

Move some debugging checks inside Py_DEBUG.

They were causing cache misses according to cachegrind.

This causes a modest speedup.

PyObject_TypeCheck() which is a macro that often avoids a call, and if
it does make a call, calls the much more efficient PyType_IsSubtype().
This saved 6% on a benchmark for slot lookups.

There's really no point in a separate list of thank-you notes.

popen2() and popen3() created text-mode pipes even when binary mode
was asked for.  This was specific to Windows.

This is a silly workaround for a rather serious bug in MacOSX: if you take
a long filename and convert it to an FSSpec the fsspec gets a magic
cooky (containing a #, indeed). If you then massage the extension of this
fsspec and convert back to a pathname you may end up referring to the
same file. This could destroy your sourcefile. The problem only occcurs
in MacPython-OS9, not MacPython-OSX (I think).

Closes bug #505562.

Jeremy reported that this is not allowed by RFC 2396; however,
other tools support unescaped @'s so we should also.

 - update DLL version number
 - add files required for 2.3 (no changes to modules though)
 - restructure build of pgen.exe

NOTE:  As I don't have the VACPP compiler, these changes are untested.
Apart from slightly re-ordering some file lists, and matching file name
casing, I believe these changes are the minimum necessary to build 2.3
with VACPP.

 - the security fixes to tempfile have lead to test_tempfile wanting
   to create 100 temporary files.  as the EMX default is only 40,
   the number of file handles has been bumped (up to 250).
 - changes to pgen have required restructuring its build support.

Also, don't call gettempdir() in the default expression for the 'dir'
argument to various functions; use 'dir=None' for the default and
insert 'if dir is None: dir = gettemptir()' in the bodies.  That way
the work done by gettempdir is postponed until needed.

subprocess that does the right checks.  This now works on Windows as
well.

com_error() is static in Python/compile.c.

Also, don't handle METH_OLDARGS on the fast path.  All the interesting
builtins have been converted to use METH_NOARGS, METH_O, or
METH_VARARGS.

Result is another 1-2% speedup.  If I can cobble together 10 of these,
it might make a difference.

This makes the code much easier to ready, because it is at a sane
indentation level.  On my box this shows a 1-2% speedup, which means
nothing, except that I'm not going to worry about the performance
effects of the change.

-- replace then with slightly faster PyObject_Call(o,a,NULL).  (The
difference is that the latter requires a to be a tuple; the former
allows other values and wraps them in a tuple if necessary; it
involves two more levels of C function calls to accomplish all that.)
