/* As a form of self-discipline, we require that the C file(s) including pre.h
 * (which is to say all C files) define whether they are building object code
 * for libraries or exectuables. By enforcing this, we can then make sure that
 * post.h doesn't expose any libsys functions for library code. The reason for
 * this is to prevent libraries having linker dependencies on libsys which is
 * *not* installed! This has already caught me out once, so this measure is
 * useful to me at least. */
