Don't use SEH when compiling wth mingw.
Use IS_INTRESOURCE to determine function name from function ordinal.

Rewrite the code that allocates and frees callback functions, hopefully
this avoids the coverty warnings: Remove the THUNK typedef, and move the

test_capi.py:  A test module should never spawn a thread as
a side effect of being imported.  Because this one did, the
segfault one of its thread tests caused didn't occur until
a few tests after test_regrtest.py thought test_capi was
finished.  Repair that.  Also join() the thread spawned
at the end, so that test_capi is truly finished when
regrtest reports that it's done.

_testcapimodule.c test_thread_state():  this spawns a
couple of non-threading.py threads, passing them a PyObject*
argument, but did nothing to ensure that those threads
finished before returning.  As a result, the PyObject*
_could_ (although this was unlikely) get decref'ed out of
existence before the threads got around to using it.
Added explicit synchronization (via a Python mutex) so
that test_thread_state can reliably wait for its spawned
threads to finish.

Make some functions static, reformat function decl to be consistent and check for error from PyModule_GetDict()

This was a fair amount of rework of the patch.  Refactored test_fork1 so it
could be reused by the new tests for wait3/4.  Also made them into new style
unittests (derive from unittest.TestCase).

 This patch adds a-LAW encoding to audioop and replaces the old
u-LAW encoding/decoding code with the current code from sox.

Possible issues: the code from sox uses int16_t.

Will backport.
