Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #14 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I think longlong.h uses these heavily and there are many copies of that. The casts serve as (admittedly ugly) type verification.
