--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Jonathan Wakely from comment #4) > (In reply to Jonathan Wakely from comment #3)You'd need to change "T > foo():" to "int foo:N" i.e. change the type, remove the parens, and add a > constant for the size. *and* add a semi-colon!
