  Remove the test file before writing it in case there is no write permission.
  This might help fix some of the failures on Windows box(es).  It doesn't hurt
  either way and ensure the tests are a little more self contained (ie have
  less assumptions).

  Applied patch #2617 from Frank Wierzbicki wit some extras from me

  Re-implement the 'warnings' module in C. This allows for usage of the
  'warnings' code in places where it was previously not possible (e.g., the
  parser). It could also potentially lead to a speed-up in interpreter start-up
  if the C version of the code (_warnings) is imported over the use of the
  Python version in key places.

  Closes issue #1631171.
