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
