I propose a simple solution - just ignore warnings in these cases.
Win32 is not an API which you could safely compile with signed/unsigned
comparison warnings turned on, there are huge amount of cases when an
API receives an unsigned int as a string length but returns signed int
as a resulting length, and vice versa. There is no any consistency with
passing/returning buffer lengths in Win32 at all, sometimes it's DWORD,
sometimes UINT, sometimes just int. And that's just a couple of examples.
