Add "-fno-strict-aliasing" to compilation flags
    
    Fixes a slew of:
      "dereferencing type-punned pointer will break strict-aliasing rules"
    warnings from GCC for lines of the form:
      Py_INCREF(Py_True);
    and
      Py_INCREF(Py_False);
    
    due to the cast from PyIntObject* to PyObject*
    
    GCC is technically correct here; see:
      http://www.python.org/dev/peps/pep-3123/
    though this is unlikely to lead to non-working machine code.
