uint_for_t

template<unsigned NBits>

using morton::detail::uint_for_t = typedef typename uint_for<NBits>::type

uint128_t

using morton::detail::uint128_t = typedef unsigned __int128

The built-in 128-bit unsigned, used for 65..128-bit codes.

__extension__ suppresses the "ISO C++ does not support '__int128'" diagnostic that GCC and Clang emit under -Wpedantic: __int128 is a compiler extension, and this is the standard portable way to say "yes, deliberately" so that consumers compiling with -Wpedantic get a clean build. It changes nothing about the type or the generated code — spelling every other use of the built-in through this alias keeps the whole library quiet.
