[Python-Dev] New Unicode warnings

[Tim Peters]

There are 3 functions now where the prototypes in unicodeobject.h don't
match the definitions in unicodeobject.c.  Like, in .h,

extern DL_IMPORT(Py_UNICODE) _PyUnicode_ToTitlecase(
    register const Py_UNICODE ch 	/* Unicode character */
    );

but in .c:

Py_UNICODE _PyUnicode_ToTitlecase(register Py_UNICODE ch)

That is, they disagree about const (a silly language idea if ever there was
one <wink>).

The others (I haven't check these for the exact reason(s), but assume
they're the same deal):

_PyUnicode_ToUppercase
_PyUnicode_ToLowercase
