: The compiler moans about (T)(-1) >= 0 as well. Is the assumption that
: (unsigned type)(-1) is never zero valid?

yes.  There are no known machines where -1 == 0 for types of different
signs.  Further, the C standard says that it must behave as if it is a
two's complement machine, and I think that C++ says so too.
