Barry, that comment belongs in the code, not in the checkin msg.
The code *used* to do this correctly (as you well know, since you
& I went thru considerable pain to fix this the first time).
However, because the *reason* for the convolution wasn't recorded
in the code as a comment, somebody threw it all away the first
time it got reworked.

comment.

ANSI specifies that pointer compares other than == and != to
non-related structures are undefined. This quiets an Insure
portability warning.
between passes: Win9x DOS boxes are limited to 50 lines max, and the result
of the first pass scrolls off irretrievably otherwise. Also simplified
the goto-laden logic a bit.

METH_VARARGS. Closes SF patch #103265.
created by Andrew's setup.py script, *if* we're actually running from
the build directory. (The test for that: whether the sys.path[-1]
ends in "/Modules".)
This has one disadvantage: it imports a fair amount of code from the
distutils package, just in order to be able to calculate the correct
pathname. See if I care. :-)
del'ing func.func_dict. I took the opportunity to also clean up some
other nits with the code, namely core dumps when del'ing func_defaults
and KeyError instead of AttributeError when del'ing a non-existant
function attribute.
Specifically,
func_memberlist: Move func_dict and __dict__ into here instead of
special casing them in the setattro and getattro methods. I don't
remember why I took them out of here before I first uploaded the PEP
232 patch. :/
func_getattro(): No need to special case __dict__/func_dict since
their now in the func_memberlist and PyMember_Get() should Do The
Right Thing (i.e. transforms NULL values into Py_None).
func_setattro(): Document the intended behavior of del'ing or setting
to None one of the special func_* attributes. I.e.:
func_code - can only be set to a code object. It can't be del'd
or set to None.
func_defaults - can be del'd. Can only be set to None or a tuple.
func_dict - can be del'd. Can only be set to None or a
dictionary.
Fix core dumps and incorrect exceptions as described above. Also, if
we're del'ing an arbitrary function attribute but func_dict is NULL,
don't create func_dict before discovering that we'll get an
AttributeError anyway.
(I realize that I didn't really test this, because all the tests
succeed, so verify() never raised an AssertionError -- but the test
suite still succeeds, so I'm not too worried.)
This patch adds support for Cygwin to util.get_platform(). A Cygwin
specific case is needed due to the format of Cygwin's uname command,
which contains '/' characters.

I agree, so am fixing this.
symbol table for each top-level compilation unit. The information in
the symbol table allows the elimination of the later optimize() pass;
the bytecode generation emits the correct opcodes.
The current version passes the complete regression test, but may still
contain some bugs. It's a fairly substantial revision. The current
code adds an assert() and a test that may lead to a Py_FatalError().
I expect to remove these before 2.1 beta 1.
The symbol table (struct symtable) is described in comments in the
code.
The changes affects the several com_XXX() functions that were used to
emit LOAD_NAME and its ilk. The primary interface for this bytecode
is now com_addop_varname() which takes a kind and a name, where kind
is one of VAR_LOAD, VAR_STORE, or VAR_DELETE.
There are many other smaller changes:
- The name mangling code is no longer contained in ifdefs. There are
two functions that expose the mangling logical: com_mangle() and
symtable_mangle().
- The com_error() function can accept NULL for its first argument;
this is useful with is_constant_false() is called during symbol
table generation.
- The loop index names used by list comprehensions have been changed
from __1__ to [1], so that they can not be accessed by Python code.
- in com_funcdef(), com_argdefs() is now called before the body of the
function is compiled. This provides consistency with com_lambdef()
and symtable_funcdef().
- Helpers do_pad(), dump(), and DUMP() are added to aid in debugging
the compiler.
