That is this thread?

This has been suggested once before (dlopen'ing a library for 
KerberosGetAFSToken) but there was not much support for it.  I suspect 
there would not be much support for this either.

I don't think Cygwin does.  There could well be others.

Even on platforms where it is supported it's likely to vary quite a bit. 
On AIX, libfoo.a can contain shared and static components.  On HP-UX, the 
libraries are libfoo.sl not libfoo.so.  dlopen can be hiding in different 
places on different platforms.  And probably many other things...

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
