I believe that this is a really, really bad idea. Sometimes, it is necessary to create an option with the specific intent that the programmer will be able to enable/disable it on a file-by-file basis by tweaking the Makefile and/or compiler command line. DIAGNOSTIC is the prime example of this sort of option---most of the time you /don't/ want it to be on in a part of the kernel other than what you're working on, and you'll probably do something like `make CC="cc -DDIAGNOSTIC"' to ensure that this is so. -GAWollman -- Garrett A.
