removing all use of signed struct values.

test_zipfile and test_zipfile64 pass.  no more warnings.

when compiled properly optimized and about the same speed otherwise.

Some people look for them in hashlib.

This work is substantially Anthony Baxter's, from issue
1633807.  I just freshened it, made a few minor tweaks,
and added the test cases.  I also created issue 2412,
which is to check for 2to3's behavior with the print
function.  I also added myself to ACKS.

Fix a buglet in binascii.crc32, the second optional argument could previously
have a signedness mismatch with the C variable its going into.

Add py3k warnings for code and method inequality comparisons. This should resolve issue 2373. The codeobject.c and methodobject.c changes are both just backports of the Python 3 code.

Fix test_atexit so that it still passes when -3 is supplied. (It was catching the warning messages on stdio from using the reload() function.)

uid and gid input to accept values >=2**31 as valid while still accepting
negative numbers to pass -1 to chown for "no change".

Fixes issue1747858.

This should be backported to release25-maint.

_have_soundcard() is a bad check for winsound.Beep, since you can have a soundcard but have the beep driver disabled. This revision basically disables the beep tests by wrapping them in a try/except. The Right Way To Do It is to come up with a _have_enabled_beep_driver() and use that.

Add py3k warnings for object, type, cell and dict comparisons. This should resolve issue2342 and partly resolve issue2373.

some verification:

- Runs reindent.py on all .py files.
- Checks if any changes in Doc exist.
- Whether Misc/ACKS was changed.
- Whether Misc/NEWS was changed.

The hope is that ``make check`` can become a command anybody can run to get
reminders about what all the requisite steps needed to create a proper
patch/checkin.

copy, now it is doing a os.rename() if it's on the same file-system.

on OS X.

Use test_support.unlink instead of os.unlink in tearDown().  (Seems to fix an occasional failure in Windows Vista.)

The removal of strerror.c led to the function check being removed from
configure.in.

It would probably be better to have a configure test for that, but
this is outside of my configure expertise.

The behaviour of winsound.Beep() seems to differ between different versions of Windows when there's either:
    a) no sound card entirely
    b) legacy beep driver has been disabled
    c) the legacy beep driver has been uninstalled
Sometimes RuntimeErrors are raised, sometimes they're not.  If _have_soundcard() returns False, don't expect winsound.Beep() to raise a RuntimeError, as this clearly isn't the case, as demonstrated by the various Win32 XP buildbots.

Issue 2286: bump up the stack size of the 64-bit debug python_d.exe to 2100000.  The default value of 200000 causes a stack overflow at 1965 iterations of r_object() in marshal.c, 35 iterations before the 2000 limit enforced by MAX_MARSHAL_STACK_DEPTH.
