Don't call sys.exit() all over the place -- simply return the exit
status from main() and call sys.exit(main()) in the startup stub at
the end of the file.

Many changes.
Change default alloc size for uncompressing to 16K.
Remove comment about core dumps when an invalid window sizes is used.
This bug has been fixed in zlib 1.0.4.
Two new optional arguments to decompress, wbits and bufsize. wbits
specifies the window size and bufsize specifies the initial output
string size.
In decompression code -- decompress and decompressobj methods -- use a
Python string (and _PyString_Resize) to collect the uncompressed
stream. Replaces a separate buffer that was copied into a string.
Fix bug in decompress that caused it to always realloc the buffer when
it was finished decompressing.
Modernized handling of optional arguments to compressobj.

Much rewritten. Added Win32 registry stuff (from getpath_nt.c, which
is now obsolete), and changed the default path calculations.
$PYTHONPATH is now added as a prefix (like it's always been on Unix);
$PYTHONHOME takes precedence over the program pathname; and only one
landmark is needed.

Made it real. Changed locking() to work with file descriptors instead
of Python file objects. Added open_osfhandle() (Mark had done some
work for that), get_osfhandle(), setmode(), and the console I/O
functions kbhit(), getch(), getche(), ungetch(), and putch().

Changes by AMK:
Removed handling of \e, \cX escapes, following a string-SIG discussion.
Fixed minor typos in re.py
re.error is now set equal to reop.error.
Move definition of constants like NORMAL and CHARCLASS into reop, which
exports them; re.py was changed to import them from reop.
Added C equivalents of _expand and expand_escape to reop, and changed
re.py to use them.

Support using -p/-P to point to the source/build directory instead of
the install directory. Added -h option to print the full usage
message; by default, only two lines are now printed for errors.

Modified for CW Pro 1 projects. Convention used: .mu files are old
project files, which have to be cleaned up before checking in, .prj
files are CW Pro 1 projects (which are always clean). Prj files are
still binhexed, even though they only have a data fork (and, hence,
could be checked in in binary mode).

Generate class, property and comparison code (finally!). The resulting
code isn't ideal yet: xxx.Window(1).Paragraph(3).font will only work
if all the classes and properties are declared in the same suite, but
at least font(Paragraph(3, Window(1))) always works.
Got the new structure working with MSVC 4.2.
main_nt.c is gone -- we can use Modules/python.c now.
Added Mark Hammond's module msvcrt.c (untested).
Added several new symbols.
Add a cast to the call to _Py_Dealloc in the expanded version of
Py_DECREF, to reduce the warnings when compiling with reference count
debugging on. (There are still warnings for each call to
_Py_NewReference -- too bad.)
New rules for deleting modules. Rather than having an elaborate
scheme based on object's types, have a simple two-phase scheme based
on object's *names*:
/* To make the execution order of destructors for global
objects a bit more predictable, we first zap all objects
whose name starts with a single underscore, before we clear
the entire dictionary. We zap them by replacing them with
None, rather than deleting them from the dictionary, to
avoid rehashing the dictionary (to some extent). */
Change the Fini function to only remove otherwise unreferenced strings
from the interned table. There are references in hard-to-find static
variables all over the interpreter, and it's not worth trying to get
rid of all those; but "uninterning" isn't fair either and may cause
subtle failures later -- so we have to keep them in the interned
table.
Also get rid of no-longer-needed insert of None in interned dict.
Provide a dummy empty directory as f_builtins instead of failing, when
no valid directory is passed in. This prevents __del__ to fail when
invoked after __builtins__ has already been discarded.
Also add PyFrame_Fini() to discard the cache of frames.
Removed fatal errors from Py_Initmodule4() (and thus from
Py_Initmodule(), which is a macro wrapper around it).
The return value is now a NULL pointer if the initialization failed.
This may make old modules fail with a SEGFAULT, since they don't
expect this kind of failure. That's OK, since (a) it "never" happens,
and (b) they would fail with a fatal error otherwise, anyway.
Tons of extension modules should now check the return value of
Py_Initmodule*() -- that's on my TODO list.
Avoid function calls to access the current thread state and builtins
-- the thread state is passed in as an argument and the builtins are a
member thereof.
Mass checkin (more to follow for other directories).
Introduce truly separate (sub)interpreter objects. For now, these
must be used by separate threads, created from C. See Demo/pysvr for
an example of how to use this. This also rationalizes Python's
initialization and finalization behavior:
Py_Initialize() -- initialize the whole interpreter
Py_Finalize() -- finalize the whole interpreter
tstate = Py_NewInterpreter() -- create a new (sub)interpreter
Py_EndInterpreter(tstate) -- delete a new (sub)interpreter
There are also new interfaces relating to threads and the interpreter
lock, which can be used to create new threads, and sometimes have to
be used to manipulate the interpreter lock when creating or deleting
sub-interpreters. These are only defined when WITH_THREAD is defined:
PyEval_AcquireLock() -- acquire the interpreter lock
PyEval_ReleaseLock() -- release the interpreter lock
PyEval_AcquireThread(tstate) -- acquire the lock and make the thread current
PyEval_ReleaseThread(tstate) -- release the lock and make NULL current
Other administrative changes:
- The header file bltinmodule.h is deleted.
- The init functions for Import, Sys and Builtin are now internal and
declared in pythonrun.h.
- Py_Setup() and Py_Cleanup() are no longer declared.
- The interpreter state and thread state structures are now linked
together in a chain (the chain of interpreters is a static variable
in pythonrun.c).
- Some members of the interpreter and thread structures have new,
shorter, more consistent, names.
- Added declarations for _PyImport_{Find,Fixup}Extension() to import.h.
