--- Comment #14 from Martin Nowak <[email protected]> --- (In reply to Martin Nowak from comment #13) > Let's please answer the question of comment 1, which typedef is active. > Looks like you have a __UINT64_TYPE__ long long unsigned int now. Indeed the __UINT64_TYPE__ isn't present on my version of XCode/clang. It seems the better fix would be to rely on <stdint.h> and always use uint64_t. That would be unsigned long long, so we'd need to change D's ulong to match that. I'll go with a workaround for newer XCode versions for now, but this needs to be sorted out clearly. --
