Either override render() for unsigned type converters, or add new converter 
attribute (in additional to "type", "cast", "conversion_fn", etc).

STINNER Victor added the comment:

It would be better to only modify clinic for unsigned types, but how do you
check if a type is signed or not?

Serhiy Storchaka added the comment:

I think this should be done only for unsigned integer types. Otherwise it just 
dirty sources and can hide actual bugs.

[issue22120] Fix compiler warnings

[STINNER Victor]

STINNER Victor added the comment:

clinic.patch: modify clinic.py to generate "return_value == (type)-1" instead 
of "return_value == -1" to avoid a warning if return_value is unsigned.
