Only if you read in reverse chronological order. Ingo's message was in reply to Linus and it received somewhat favorable replies and was not shot down. I certainly do not see sufficient consensus to go around changing code other people maintain. My suggest has the nice property that it handles all 512 different combinations. I think that was the only real downside of Ingo's suggestion. There are just too many different combinations to define a set of macros to cover all of the cases. Eric
