--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
GCC is correct here.  Pasting of :: and ClassFOO1 don't make a valid
preprocessing token.

That is you don't need the pasting operator between :: and k here.
The pasting operator is used to paste together two identifiers to make one.
