Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Note the UNUSED macro (whether function-like or not) certainly doesn't belong to headers included from STL headers either. It should have been __gthr_unused or something similar.
