I did specifically check the compiler defined macros I could see in the AST and 
they were not diagnosed from the beginning.
I would guess, only the compiler-flag macros are passed in the PPCallbacks, 
which would explain the current behaviour.

It is a burden with little to gain as they the toggle-stuff use-case is not 
replaceable with other constructs.
Having it as opt-in might be ok, but by default the check should not diagnose 
them.
