I see the problem, but as far as I understand, this is not unique to libC or Posix. Any libraries that use non-primitive types (which is most of them) will suffer from the very same problem. So I anticipated that this type lookup from the ASTContext needs to be implemented regardless of the irrelevant signature functionality.
