ANSI says: An object declared as type _Bool is large enough to store the values 0 and 1. gcc spec doesn't say anything, but: $ gcc -S -x c -o - - unsigned long x = sizeof(_Bool); ^D .... x: .quad 1 I.e. sizeof(_Bool) = 1 byte. > Could you please try changing ever 'bool' in that file to 'unsigned long' > and see if that fixes it?

Yes, that fixes it. We even had someone sending that fix a while ago, but it seems it's not applied to Jens' tree yet and I can't find it anymore either right now. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
