I don't understand this sentence.

I understand your question now. The equivalence of the function
declarations is a rule specific to overloading (13.1/3), which does
not apply here. When two argument lists are considered equivalent for
the purposes of partial specialization should be covered by 14.5.4,
and I don't see any statement there to indicate that T* and T[] are to
be treated as equivalent.

Better evidence, of course, is that Howard says its okay. :-)
