Subject: PyUnicode_EncodeUTF8:  squash compiler wng.  The difference of two
X-Git-Tag: v2.3c1~5858

PyUnicode_EncodeUTF8:  squash compiler wng.  The difference of two
pointers is a signed type.  Changing "allocated" to a signed int makes
undetected overflow more likely, but there was no overflow detection
before either.
