In version 2.4, this printed "None", restored that behavior.

hopes that more information will help debug the failing test on HPPA Ubuntu.

of PY_FORMAT_SIZE_T to "l" for Mac OSX.  I don't know a better define
to use.  This should get rid of the warnings on other platforms and Mac too.

These tests should be improved.  Hopefully this fixes variations when
flipping back and forth between fpdef and fplist.

Backport candidate.

In addition to testing positive numbers, verify negative numbers work in configure.
In order to avoid compiler warnings on OS X 10.4, also change the order of the check
for the format character to use (PY_FORMAT_SIZE_T) in the sprintf format
for Py_ssize_t.  This patch changes PY_FORMAT_SIZE_T from "" to "l" if it wasn't
defined at configure time.  Need to verify the buildbot results.

Backport candidate (if everyone thinks this patch can't be improved).

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.

(Also fix some whitespace)

Klocwork #364.

As mentioned on python-dev, reverting patch #1504333 because it introduced
an infinite loop in rev 47154.

This patch also adds a test to prevent the regression.

on exception classes.  Would require introducing a tp_unicode slot to make it
work otherwise.

Fixes bug #1551432 and will be backported.
