Then, how do you do the extra linking? What is producing the "Cygwin 
runtime failure" message when loading/linking a DLL fails?

The medium model in Clang is not wasteful. It does exactly what it is 
designed to do. It was never designed with Cygwin in mind. The program 
build with a medium model is wasteful because it makes all addresses 64 
bits when few or no addresses actually need to be 64 bits.

It is not for my own project. I am writing manuals on how to optimize 
software.
