I know my example is very wrong; though it could be used to grep for optimizer flags, where it could not be used for what I jokingly said it could be used for... I guess it was too subtle. Question: -O0 fails to produce good code; how do I check and warn if -O0 is being used? Answer: Fix -O0, or grep its use and complain about it Answer 2: Make its use an argument error to the compiler, until it is fixed Answer 3: Quit munging the Makefiles, when they will just need to be unmunged later, and the problem goes away if you change the compiler -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
