Two warnings under NVCC

[henryiii]

When compiling with CUDA 8 and moving from fmt 4 to 5, I get hundreds of pages of warnings that I think boil down to two:

1

extern/fmt/include/fmt/core.h(978): warning: integer conversion resulted in a change of sign

fmt/include/fmt/core.h

Lines 976 to 979 in 5386f1d

	static FMT_CONSTEXPR uint64_t get_types() {
	return IS_PACKED ? internal::get_types<Context, Args...>()
	: -static_cast<int64_t>(NUM_ARGS);
	}

I'm not sure how this could be correct, -int is returned as uint without explicit cast?

2

extern/fmt/include/fmt/core.h(791): warning: nonstandard use of "auto" to both deduce the type from an initializer and to announce a trailing return type

fmt/include/fmt/core.h

Lines 789 to 797 in 5386f1d

	basic_format_arg<Context> find(basic_string_view<char_type> name) const {
	// The list is unsorted, so just return the first matching name.
	for (auto it = map_, end = map_ + size_; it != end; ++it) {
	if (it->name == name)
	return it->arg;
	}
	return basic_format_arg<Context>();
	}
	};

Could this odd auto and comma be replaced by a decltype? (and comma, unfortunately)

Fixed in 911a751, thanks.
