There are other requirements besides getting the library to
build. Before we can open up the library on Solaris for
possible consumption by others, we will need to decide which of the interfaces
in these libraries are public and which are private, and what is the
stability level of the interfaces. Any public interface changes
to the libraries will need to be approved by PSARC. There are other
rules on shared objects which we must follow, even if we put the
shared libraries out on /usr/lib and make all the interfaces private.
If we keep the libraries within usr/src/cmd/ksh for now we don't
have to worry about it yet.
