comparison Include/Python.h @ 31250:dfd0114cf9ec legacy-trunk

There are places in Python which assume bytes have 8-bits. Formalize that a bit by checking the value of UCHAR_MAX in Include/Python.h. There was a check in Objects/stringobject.c. Remove that. (Note that we don't define UCHAR_MAX if it's not defined as the old test did.)
