was a mistake of mine in updating patch #975056 (I think).

this test failed under the combination of passing -O to a debug-build
Python.  Now all 4 of those pass ({debug, release} x {-O, no -O}).

rangeobject.c has an #ifdef that is reached only when LONG_MAX != INT_MAX

Easy doc corrections from Dan Gass.
Also repaired the LaTeX for optional keyword arguments throughout, which
was (incorrectly) nested instead of flat.

73: Restore support for Python 2.1.
74: Factor the previous change differently
79: Conditionalize usage of PyTuple_Pack.

want to use pywin32 instead of _subprocess, you have to edit the file.

Python's own setup.py that did the same thing (and tested on Solaris,
where LDSHARED is needed...)

a few remaining calls to signal() were converted to PyOS_setsig().

non-ascii characters.

This support was only a first cut, and doesn't deserve to be in
a released version (where we have to support it in an ongoing
manner)

it's rather expensive to create new processes.

for another day.)

debug build on Windows now.  More applications of the helper may be needed
on non-Windows platforms.

Turns out the mysterious "expected output" file contained exactly N dots,
because test_poll() has a loop that *usually* went around N times,
printing one dot on each loop trip.  But there's no guarantee of that,
because the exact value of N depended on the vagaries of scheduling
time.sleep()s across two different processes.  So stopped printing dots,
and got rid of the expected output file.  Add a loop counter instead,
and verify that the loop goes around at least a couple of times.  Also
cut the minimum time needed for this test from 4 seconds to 1.

of the test.  It's testing stdout in a different process, so it has to
print something, but I didn't find "banana" to be self-explanatory.

tester that a DOS box is expected to flash.  Slash the sleep from 2
seconds to a quarter second (why would we want to wait 2 seconds just
to stare at a DOS box?).

what this is trying to do.  If it's necessary for it to create > 1000
processes, it should be controlled by a new resource and not run by
default on Windows.

display a test's docstring as "the name" of the test.  So changed most
test docstrings to comments, and removed the clearly useless ones.  Now
unittest reports the actual names of the test methods.

of this should be on non-WIN32 Windows variants.

Bug fixes:

* Use fresh copy of globals/locals so the script being debugged can't access
  the pdb namespace (e.g.: p line_prefix will no longer work).

* Remove pdb.py's path from sys.path. Having it in there is normally not a
  problem, but it could prove irritating when messing with PYTHONPATH or
  invoking pdb via /usr/bin/pdf.

* You can now set a breakpoint on the script being debugged, even if the script
  doesn't end with a '.py' extension. Also, setting breakpoints with absolute
  paths now works reliably.

Enhancements:

* Go directly to the first line of the script.

* Enter post-mortem debugging if the script being debugged doesn't catch an
  exception.

* Restart the script being debugged and preserve debugger state when the script
  being debugged exits.

Cleanup:

* Moved the __main__ method into a main() function.

* Kill the (undocumented, not in __all__) mainmodule/mainpyfile globals, add a
  mainpyfile attribute to pdb.

Thanks Ilya Sandler for the patch!
