The question is not whether it is signed, it is whether it is a signed
integral type. The standard says:

1) There are four signed integral types: signed char, short int, int, and
long int. [3.9.1]

2) Each cv-unqualified type has three cv-qualified "versions" of its type:
a const version, a volatile version, and a const volatile version. However
these are distinct types. [3.9.3]

Miller seems to think this can be read as allowing const int to be a signed
integral type, but I still don't buy it.
