  Include <alloca.h> on Solaris, see issue #1506.

  It would probably be better to have a configure test for that, but
  this is outside of my configure expertise.
........
  r61523 | brett.cannon | 2008-03-18 16:35:58 +0100 (Di, 18 Mär 2008) | 5 lines

  Remove all traces of HAVE_STRERROR.

  The removal of strerror.c led to the function check being removed from
  configure.in.
........
  r61524 | brett.cannon | 2008-03-18 16:52:00 +0100 (Di, 18 Mär 2008) | 2 lines

  Fix test_errno to only check for error numbers that are defined by Standard C.
........
  r61525 | steven.bethard | 2008-03-18 17:00:19 +0100 (Di, 18 Mär 2008) | 1 line

  Use test_support.unlink instead of os.unlink in tearDown().  (Seems to fix an occasional failure in Windows Vista.)
........
  r61526 | brett.cannon | 2008-03-18 17:47:51 +0100 (Di, 18 Mär 2008) | 3 lines

  Cast the arguments to PyString_AsStringAndSize() to silence compiler warnings
  on OS X.
........
  r61527 | sean.reifschneider | 2008-03-18 18:24:12 +0100 (Di, 18 Mär 2008) | 3 lines

  Issue 1577: shutil.move() where destination is a directory was doing a
  copy, now it is doing a os.rename() if it's on the same file-system.
........
  r61528 | brett.cannon | 2008-03-18 18:25:13 +0100 (Di, 18 Mär 2008) | 12 lines

  Add Tools/scripts/patchcheck.py. Invoked from ``make check``, the script does
  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.

  Get regrtest working when re-running tests
