--- Comment #11 from Jakub Jelinek <jakub at gcc dot gnu.org> --- OT, the gcc/config/s390/linux.h SIZE_TYPE definition looks weird: (TARGET_64BIT ? "long unsigned int" : "long unsigned int") As both strings are the same, it would be much cleaner to just say "long unsigned int" Now everybody reading it will just try to spot the changes between those 2 strings.
