x**2 should about equal x*x (including for a float x such that the result is
inf) but didn't; added a test to test_float to verify that, and ignored the
ERANGE value for errno in the pow operation to make the new test pass (with
help from Marilyn Davis at the Google Python Sprint -- thanks!).

Bug fixes large and small for tokenize.
Small: Always generate a NL or NEWLINE token following
a COMMENT token. The old code did not generate an NL token if
the comment was on a line by itself.
Large: The output of untokenize() will now match the
input exactly if it is passed the full token sequence. The
old, crufty output is still generated if a limited input
sequence is provided, where limited means that it does not
include position information for tokens.
Remaining bug: There is no CONTINUATION token (\) so there is no way
for untokenize() to handle such code.
Also, expanded the number of doctests in hopes of eventually removing
the old-style tests that compare against a golden file.
Bug fix candidate for Python 2.5.1. (Sigh.)

Replace dead code with an assert.
Now that COMMENT tokens are reliably followed by NL or NEWLINE,
there is never a need to add extra newlines in untokenize.

Reverting the patch that tried to fix the issue whereby x**2 raises
OverflowError while x*x succeeds and produces infinity; apparently
these inconsistencies cannot be fixed across ``all'' platforms and
there's a widespread feeling that therefore ``every'' platform
should keep suffering forevermore. Ah well.

Hmm, this test has failed at least twice recently on the OpenBSD and
Debian sparc buildbots. Since this goes through a lot of tests
and hits the disk a lot it could be slow (especially if NFS is involved).
I'm not sure if that's the problem, but printing periodic msgs shouldn't hurt.
The code was stolen from test_compiler.

"Conceptual" merge of rev 51711 from the 2.5 branch.
i_divmod(): As discussed on Python-Dev, changed the overflow
checking to live happily with recent gcc optimizations that
assume signed integer arithmetic never overflows.
This differs from the corresponding change on the 2.5 and 2.4
branches, using a less obscure approach, but one that /may/
tickle platform idiocies in their definitions of LONG_MIN.
The 2.4 + 2.5 change avoided introducing a dependence on
LONG_MIN, at the cost of substantially goofier code.

Bug #1520864 (again): unpacking singleton tuples in list comprehensions and
generator expressions (x for x, in ... ) works again.
Sigh, I only fixed for loops the first time, not list comps and genexprs too.
I couldn't find any more unpacking cases where there is a similar bug lurking.
This code should be refactored to eliminate the duplication. I'm sure
the listcomp/genexpr code can be refactored. I'm not sure if the for loop
can re-use any of the same code though.
Will backport to 2.5 (the only place it matters).

Forward-port of rev. 51857:
Building with HP's cc on HP-UX turned up a couple of problems.
_PyGILState_NoteThreadState was declared as static inconsistently.
Make it static as it's not necessary outside of this module.
Some tests failed because errno was reset to 0. (I think the tests
that failed were at least: test_fcntl and test_mailbox).
Ensure that errno doesn't change after a call to Py_END_ALLOW_THREADS.
This only affected debug builds.

for Py_ssize_t. This patch changes PY_FORMAT_SIZE_T from "" to "l" if it wasn't

Forward-port of r52136,52138: a review of overflow-detecting code.
* unified the way intobject, longobject and mystrtoul handle

* in general, trying to entierely avoid overflows in any computation
involving signed ints or longs is extremely involved. Fixed a few
simple cases where a compiler might be too clever (but that's all
guesswork).
* more overflow checks against bad data in marshal.c.
* 2.5 specific: fixed a number of places that were still confusing int
and Py_ssize_t. Some of them could potentially have caused
"real-world" breakage.
* list.pop(x): fixing overflow issues on x was messy. I just reverted
to PyArg_ParseTuple("n"), which does the right thing. (An obscure
test was trying to give a Decimal to list.pop()... doesn't make
sense any more IMHO)

Remove file-locking in MH.pack() method.
This change looks massive but it's mostly a re-indenting after
removing some try...finally blocks.
Also adds a test case that does a pack() while the mailbox is locked; this
test would have turned up bugs in the original code on some platforms.
In both nmh and GNU Mailutils' implementation of MH-format mailboxes,
no locking is done of individual message files when renaming them.
The original mailbox.py code did do locking, which meant that message
files had to be opened. This code was buggy on certain platforms
(found through reading the code); there were code paths that closed
the file object and then called _unlock_file() on it.
Will backport to 25-maint once I see how the buildbots react to this patch.
