The following simple example compiles with both
 Lucid's lcc and GNU's g++, but fails with Sun's
 cfront based compiler. Should this work?

     thanks,

PS: the error which the Sun compiler generates is:
--------------------------------------------------
"dum.cc", line 10: error:  function template parameter t must be used in signature of  dum()
