Well, SHARED libraries are supported on many UNIX and UNIX-like
operating systems, but not on all (eg. Ultrix doesn't have them)

Dynamic Loadable Libraries (with load-on-request semantics) are
supported by no UNIX system that I know of out of the box, though
there are solutions for some architectures (most prominently the
GNU dld stuff).
Some people have programmed their own DLL support which may (or
may not) be portable between different architectures.

Also, I'd like to see a very thorough security analysis of DLLs
under Unix of people who know what they are doing before I'd trust
them for security related stuff.
