discussion on python-dev. 'from mod import *' is still banned except
at the module level.
Fix value for special NOOPT entry in symtable. Initialze to 0 instead
of None, so that later uses of PyInt_AS_LONG() are valid. (Bug
reported by Donn Cave.)
replace local REPR macros with PyObject_REPR in object.h
internal states. Put the old .seed() (which could only get at about
the square root of the # of possibilities) under the new name .whseed(),
for bit-level compatibility with older versions. This occurred to me
while reviewing effbot's book (he found himself stumbling over .seed()
more than once there ...).
I'm now checking it in. I need to write some documentation for it,
but I don't have time right now. Still, I wanted to get this into
2.1a2.
# Overview:
#
# This file implements the minimal SMTP protocol as defined in RFC 821. It
# has a hierarchy of classes which implement the backend functionality for the
# smtpd. A number of classes are provided:
#
# SMTPServer - the base class for the backend. Raises an UnimplementedError
# if you try to use it.
#
# DebuggingServer - simply prints each message it receives on stdout.
#
# PureProxy - Proxies all messages to a real smtpd which does final
# delivery. One known problem with this class is that it doesn't handle
# SMTP errors from the backend server at all. This should be fixed
# (contributions are welcome!).
#
# MailmanProxy - An experimental hack to work with GNU Mailman
# <www.list.org>. Using this server as your real incoming smtpd, your
# mailhost will automatically recognize and accept mail destined to Mailman
# lists when those lists are created. Every message not destined for a list
# gets forwarded to a real backend smtpd, as with PureProxy. Again, errors
# are not handled correctly yet.
- All constructors grow an optional argument `factory' which is a
callable used when new message instances are created by the next()
methods. Defaults to the rfc822.Message class.
- A new subclass of UnixMailbox is added, called PortableUnixMailbox.
It's identical to UnixMailbox, but uses a more portable test for
From_ delimiter lines. With PortableUnixMailbox, any line that
starts with "From " is considered a delimiter (this should really
check for two newlines before the F, but it doesn't.

This involves changing the zlib build process to build zlib itself from sources, then use that library. Also updated are the comments to reflect the new official home of zlib, and add Windows specific notes regarding the build process.
"Partial" as the code uses sys.prefix in an attempt to locate 'w9xpopen.exe', but sys.prefix is not set if Python can't find it itself. So this _still_ fails in Pythonwin, but I am committing the patch for 2 reasons:
* Embedded apps that set sys.prefix or use PYTHONHOME will work
* The exception raised on failure to find the executable is far more obvious
reference manual but not checked: Names bound by import statemants may
not occur in global statements in the same scope. The from ... import *
form may only occur in a module scope.
I guess these changes could break code, but the reference manual
warned about them.
Several other small changes
If a variable is declared global in the nearest enclosing scope of a
free variable, then treat it is a global in the nested scope too.
Get rid of com_mangle and symtable_mangle functions and call mangle
directly.
If errors occur during symtable table creation, return -1 from
symtable_build().
Do not increment st_errors in assignment to lambda, because exception
is not set.
Add extra argument to symtable_assign(); the argument, flag, is ORed
with DEF_LOCAL for each symtable_add_def() call.
This change eliminates an extra malloc/free when a frame with free
variables is created. Any cell vars or free vars are stored in
f_localsplus after the locals and before the stack.
eval_code2() fills in the appropriate values after handling
initialization of locals.
To track the size the frame has an f_size member that tracks the total
size of f_localsplus. It used to be implicitly f_nlocals + f_stacksize.
