In more or less the same time frame, the AT&T UnixPC / 3B1, which was
OEM'ed from Convergent, had shared libraries. This was ~ 1986.
I don't know the details of how it worked and how one built the shared
libraries; I am sure that it was an independent implementation from Sun's.
This was done on top of a System V Release 2 kernel. Later versions
of the OS had some bits of the SVR3 user land, but the kernel remained
SVR2 based.
There is a 3B1 emulator and disk images for it available for anyone
who really wants to go back to a system with short filenames and no
job control. :-)
