Note that the author is Tavis Ormandy, the guy who (among many, many other things) discovered one of the worst Windows security vulns, that was patched last month -- and from the README it seems like this is part of the toolchest he used for this particular discovery. To all people wondering why not wine or winelib - this is for ease of debugging and fuzzing DLLs, not for actually running software. Wine and Winelib bring way too much baggage for those uses.
