Inspecting portfiles is not sufficient. You'd also have to look at each port's build system to verify that it invokes the compiler with the correct options.

The "correct" way of conditionalizing based is with the platform command, but it's often not flexible enough. For instance, it can't express "apply this script on Darwin 12 and earlier". Using the variable is also just cleaner in many cases.
