Does the pANS still guarantee that the chars used in C programming (letters,
numbers, !@#$%^&*()_+ etc.) are non-negative?  K&R-1 made such a guarantee,
and it seems to be true on all "real" machines.  Only signed-byte machines
using EBCDIC and machines that use neither ASCII nor EBCDIC would violate
this rule.
