-Wpedantic isn't a thing; you need to name the specific individual 
warnings that actually occur.  These names should be included in the 
compiler output.

And as Andrey noted, to do this properly you'd need to push/pop the 
warning status to avoid affecting the rest of the translation unit, 
including user code.

(This means that at best you can only disable warnings for internal 
usage, not for user usage.  But that's as it should be.  And you should 
verify that whatever you do *doesn't* hide the warnings in user code, 
otherwise you're just creating a different kind of problem.)
