Period. As far as the C standard is concerned, there is no relationship between comparison on pointers and comparison of their values casted to uintptr_t. The address space needn't be linear and on some machines it isn't. So speaking about signedness of pointer comparisons doesn't make sense, except for concrete implementations.
