--- Comment #2 from Yann Droneaud <yann at droneaud dot fr> ---
I stumbled upon this issue again when dealing with uint64_t as sometimes it's
defined as unsigned long, sometimes it's defined as unsigned long long
depending on the ABI. Having __builtin_ffs64(), __builtin_clz64(),
__builtin_ctz64(), etc. would ease me making my code portable to unpleasant ABI
such as Microsoft Windows ones without having to use GCC's
__builtin_types_compatible_p() (which is not supported when compiling C++), or
C11 _Generic() ...
