One good example would be in programs that allow plug-ins.  If
dlopen() was considered "linking" then one can not write a 
plug-in for GIMP unless it was under the GPL like Gimp.  I'm
not sure what license GIMP is under.


Maybe there are other ways to this. Using IPC to somehow communicate
to the symbol to execute code in that function but not using any
form of linking.
