On systems where
int8_t
is defined aschar
, the{S,Uns}erialize(Stream&, signed char)
functions become undefined.This PR resolves the issue by testing
{S,Uns}erialize(Stream&, int8_t)
instead.No behavior change on systems where
int8_t
is defined assigned char
, which is the case for most other systems.Fixes #29884.
An alternative approach is mentioned in #29884 (comment) as well.
