platforms.  The previous code was fragile, depending on the twin
accidents that:

  (1) in C, casting the double value 2.**63 to long returns the integer
      value -2**63, and
  (2) in Python, hash(-2**63) == hash(2**63).

There's already a test for this in test_hash.

Issue 4195: Restore the ability to execute packages with the -m switch (but this time in a way that leaves the import machinery in a valid state). (Original patch by Andi Vajda)

empty file is sloppy and non-portable.  Use NamedTemporaryFile to make
an empty file.

having the system table differentiate between explict and implicit globals.

#3986 replacing string and types call (like in the Py3k branch), and put exec_msg call at the right place

the only user of this is Lib/distutils/tests/test_build_ext.py (in order
to find the source for xxmodule.c).  I'm not sure if other platforms
need similar tweaks, I'm not brave enough to attempt it without being
able to test.

hacks.  The new code is based on issue #2472 posted by Antoine Pitrou.  I
did some further cleanups of the pyassem code and optimized the block
ordering pass.

Fix a number of Win32ErrorTests error cases.  chmod wasn't being tested.  'access' never raises an error.

source directory.  Mainly use 'srcdir' rather than os.getcwd() or
'.'.

Since "srcdir" should now be defined on all platforms, use it to
find the module source.
