They are not explicitly uint/ulong ext.
They use size_t and ptrdiff_t.

Basically the definition is:

version(X86_64) {
	alias size_t = ulong;
	alias ptrdiff_t = long;
} else version(X86) {
	alias size_t = uint;
	alias ptrdiff_t = long;
}


uint conversion to ulong is fine.
ulong to uint isn't. So if you really really want to use uint's. Just cast.
