093abe005d eval_code2(): Guido provides this patch for his suggested elaboration
of extended print.  If the file object being printed to is None, then
sys.stdout is used.

dd13e4f91f Replace the run-time 'future-bytecode-stream-inspection' hack to find out
how 'import' was called with a compiletime mechanism: create either a tuple
of the import arguments, or None (in the case of a normal import), add it to
the code-block constants, and load it onto the stack before calling
IMPORT_NAME.

e753ef8d1b Re-allow 'import mod.submod as s', and change its meaning to what it should
mean; the same as 'from mod import submod as s'.

0df002c45b Add three new APIs: PyRun_AnyFileEx(), PyRun_SimpleFileEx(),
PyRun_FileEx().  These are the same as their non-Ex counterparts but
have an extra argument, a flag telling them to close the file when
done.

Then this is used by Py_Main() and execfile() to close the file after
it is parsed but before it is executed.

Adding APIs seems strange given the feature freeze but it's the only
way I see to close the bug report without incompatible changes.

b59290f5b2 Fix allowable node-types for assignment, need to add 'listmaker'.
(This fix is a bit broken, just as the test already was: the test for
testlist and listmaker are done always, whereas the test for exprlist and
the actual abort() are only done if Py_DEBUG is defined. Suggestions
welcome, I guess ;)

ef8ace3a6f Charles G. Waldman <cgw@fnal.gov>:
Add the EXTENDED_ARG opcode to the virtual machine, allowing 32-bit
arguments to opcodes instead of being forced to stick to the 16-bit
limit.  This is especially useful for machine-generated code, which
can be too long for the SET_LINENO parameter to fit into 16 bits.

This closes the implementation portion of SourceForge patch #100893.

635f6fb0e9 This patch partly (some stuff went in already) ports Python to Monterey.
- Fix bug in thread_pthread.h::PyThread_get_thread_ident() where
  sizeof(pthread) < sizeof(long).
- Add 'configure' for:
	- SIZEOF_PTHREAD is pthread_t can be included via <pthread.h>
	- setting Monterey system name
	- appropriate CC,LINKCC,LDSHARED,OPT, and CCSHARED for Monterey
- Add section in README for Monterey build

24703a02e7 com_print_stmt(): Guido rightly points out that the stream expression
in extended prints should only be evaluated once.  This patch plays

0400515ff0 Fix the bug Sjoerd Mullender discovered, where find_from_args() wasn't
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.

8bad612881 Disallow "import mod.submod as m", because the result is ambiguous. Does it
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.

5ca1ef9238 comples_from_string(): Move s_buffer[] up to the top-level function

5215225ea1 Apply SF patch #101135, adding 'import module as m' and 'from module import
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.

77c9f50422 SyntaxError__str__(): Fix two memory problems discovered by Insure.
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.

ccede59889 The attempt to protect against MS_WIN16 compilers that do not support long
string literals has not been tested on an MS_WIN16 platform; the trailing
";" was inside the #ifndef MS_WIN16, which should cause an error (missing
semi-colon) when compiled with that symbol #defined.
