eval_code2(): Implement new bytecodes PRINT_ITEM_TO and
PRINT_NEWLINE_TO, as per accepted SF patch #100970.
Also update graminit.c based on related Grammar/Grammar changes.
trying hard enough to find out what the arguments to an import were. There
is no test-case for this bug, yet, but this is what it looked like:
from encodings import cp1006, cp1026
ImportError: cannot import name cp1026
'__import__' was called with only the first name in the 'arguments' list.
load mod.submod as m, or mod as m ? Both can be achieved differently, and
unambiguously. Also attempt to document this restriction (editor
appreciated!)
Note that this is an artificial check during compile, because incorporating
this in the grammar is hard, and then adjusting the compiler to do the right
thing with the right nodes is harder.
scope. Previously, s_buffer[] was defined inside the
PyUnicode_Check() scope, but referred to in the outer scope via
assignment to s. This quiets an Insure portability warning.
name as n'. By doing some twists and turns, "as" is not a reserved word.
There is a slight change in semantics for 'from module import name' (it will
now honour the 'global' keyword) but only in cases that are explicitly
undocumented.
First, the allocated buffer was never freed after using it to create
the PyString object. Second, it was possible that have_filename would
be false (meaning that filename was not a PyString object), but that
the code would still try to PyString_GET_SIZE() it.

signed chars).

string literals has not been tested on an MS_WIN16 platform; the trailing

I'm not sure what to do with Tools/compiler/compiler/* -- that isn't part of
distutils, is it ? Should it try to be compatible with old bytecode version ?
-32768..65535 is acceptable. Added B specifier (with values from
-128..255). No L added (which would have completed the set) because l
already accepts any value (and the letter L is taken for quadwords).
python-dev discussion.
This should catch future version incompatibilities on Windows. Alas,
this doesn't help for 1.5 vs. 1.6; but it will help for 1.6 vs. 2.0.
the Python Unicode implementation.
The internal buffer used for implementing the buffer protocol
is renamed to defenc to make this change visible. It now holds the
default encoded version of the Unicode object and is calculated
on demand (NULL otherwise).
Since the default encoding defaults to ASCII, this will mean that
Unicode objects which hold non-ASCII characters will no longer
work on C APIs using the "s" or "t" parser markers. C APIs must now
explicitly provide Unicode support via the "u", "U" or "es"/"es#"
parser markers in order to work with non-ASCII Unicode strings.
(Note: this patch will also have to be applied to the 1.6 branch
of the CVS tree.)

builtin_zip(): New function to implement the zip() function described
in the above proposal.
zip_doc[]: Docstring for zip().
builtin_methods[]: added entry for zip()
for systems that are missing those declarations from system include files.
Start by moving a pointy-haired ones from their previous locations to the
new section.
(The gethostname() one, for instance, breaks on several systems, because
some define it as (char *, size_t) and some as (char *, int).)
I purposely decided not to include the summary of used #defines like Tim did
in the first section of pyport.h. In my opinion, the number of #defines
likedly to be used by this section would make such an overview unwieldy. I
would suggest documenting the non-obvious ones, though.
good C practice hasn't been available to everything all along.
Added Py_SAFE_DOWNCAST(VALUE, WIDE, NARROW) macro to pyport.h; this
just casts VALUE from type WIDE to type NARROW, but assert-fails if
Py_DEBUG is defined and info is lost due to casting.
Replaced a line in Fredrik's fix to marshal.c to use the new macro.
MAGIC number. When updating it next time, be sure it's higher than 50715 *

algorithm.)
