First, a friendly smack for using a WinDoze term (DLL).... "Thwack!"

Second, an answer.

Yes, they are supported...  Take a look at the man page for "dlopen".  I
just had a need to (finally) use dynamically loadable objects in a
program, and they're pretty easy to implement.  (The "dlopen" and related
functions apply to most modern UNIX variants.)
