Please can you not mix adjustments to existing type definitions into a patch adding a new type? __UINTPTR_TYPE__, as said in prior discussions and other than __PTRDIFF_TYPE__, is not provided unconditionally by gcc (and I didn't try to work out the condition(s) so far), so use of it may introduce a regression (manifesting as a build failure somewhere). Therefore, if we are to indeed go this route, we should at least leave ourselves the option of easily reverting one change without the other.
