What is the history of shared objects on Unix? When did they first

format doesn't seem to support them. I don't recall if COFF does.
IRIX 4 had COFF shared libraries, barely. The OS included libc_s, libgl_s,
and maybe one or two other things. They were very difficult and
time-consuming to create, and if you had external dependencies then things
were even worse.
