Overflow on signed integers is undefined behavior. Perl does whatever the underlying compiler does in this case. Previously this file used a wildcard which could specify more functions than we really expect to see this potential overflow from. It is safer to mention explicitly all the functions.

# Unfortunately there doesn't seem to be any way to disable just specific

# nor =signed-integer-overflow worked.
