Raised from editorial issue #5240.
The phrase "signed basic integral types" in 31.2.2 [stream.types] has been present since C++98 but never defined. It is unclear whether "basic integral types" are "standard integer types" or "integer types" (including extended integer types). As std::streamoff should be wide enough to represent the largest possible file size, and std::uintmax_t is used as the return type of std::filesystem::file_size, we should not disallow std::streamoff to be an extended integer type which may be wider than long long. On the other hand, as std::size_t and std::ptrdiff_t have already been allowed to be extended integer types, std::streamsize should also be allowed to be an extended integer type for consistency. So I think we should just use "signed integer types" instead of "signed basic integral types" in 31.2.2 [stream.types].[2022-05-17; Reflector poll]
