Bug description:
  I did a test build, upgrading to Cython 0.15 (the current latest).
  They changed the code so that now variables are no longer implicitly
  initialized. eg:

  cdef foo

  if foo is not None:
  ...

  In earlier Cython (and Pyrex) objects were always initialized to None,
  and other variables to a reasonable default (pointers to NULL, etc).

  The one bit I investigated was spurious, the variable was being set by
  a function call as an 'out' parameter. However, there were about 10
  warnings, and it would be nice to be warning free.

  This would apply to older versions of bzr as well, since the windows
  build host uses the same version of Cython across all versions.
