For Sun, this will be fixed in the forthcoming SunOS 4.0 release with
their shared library support.  SVr3 also has this feature.  It is a real
win with almost no drawbacks when done with OS support.  Jeez Loise,
even _VMS_ has had them for years.  The only complication is version
control, and it's not _that_ hard to do.

It's best when users can define and install their own libraries too.
