Conditional compilation actionscript and annotator inspection errors

Hello,

I have a Flex project in which I am using conditional compiler directive to build several versions of the software.

When I run an inpsection on a source file I still get a lot of warnings, about code that is not relevant due to the conditional compiler directive. I have included the directive in "Project Structure -> Modules -> Compiler Options -> Conditional compiler definitions" and set it to false. Stil the inspection is inspecting code that is not relevant. Specifically errors messages from "Annotator Inspection". 

This is IntelliJ 2016.3.5

Is there a way to get rid of the warnings/errors? If the answer is: disable Annotator Inspection, can you tell me what I am missing out after that? Is it save to disable that inspection?

Thanks a lot. IntelliJ is great!!
