You can use GCC option -fexceptions during compilation of
C code to make it support exception unwinding.  But after 
looking at the glibc dlcose  source code, I think throwing 
exception through this function could leave some glibc 
internal data structure messed up.  You should catch all 
exceptions in your library __fini_Lib instead.
