Subject: [PATCH] mingw-w64: Depend on own headers derivation
Without this, a `#include <float.h>` resolves incorrectly. Either the
headers weren't on the include path at all, or they only were for
local, not system, imports.
What's weird is this used to not be a problem. Not sure what other
change in e.g. cc-wrapper would affect this.
