That was one of the points I was making earlier, I don't think we should.

We shouldn't:
 1. Create new syntax for old options, especially if they're legacy GCC ones
 2. Make it easier for people to use deprecated options

If they have to change their build systems, lets make it only one
change, for the right option.

cheers,
