I am not a C programmer by any stretch of imagination so although your
explanation seems to make sense I can not comment :-).
Good news is that the patch almost worked.  I had to tweak it a little
to appease the MS compiler.  See attached.

test_timetype.py run in isolation passes all 12 tests.
test_all.py is not so lucky.  There is about 75 file permission errors
showing during tear down but it must be something silly.  I will have
a look at it and report back.
