[issue1616] compiler warnings

[Ezio Melotti]

After fixing some warning on _cursesmodule.c in r78900 I found this issue and generated an updated list of all the warnings on trunk on the buildbots. When two or more buildbots had the same warnings I grouped them together, showing the url of the buildbot first and then the warnings.
