Thank, drug.
I think some like this:

   env DFLAGS=-wi dub run

or like this

   "buildRequirements": [ "allowWarnings" ]

without gfm/sdl2/timer.d editing.

Yes, you right. It can be removed. I will do it.

         try
         {
             SDL2Timer timer = cast(SDL2Timer)param;
             return timer.onTimer(interval);
         }
         catch (Throwable e)
         {
             // No Throwable is supposed to cross C callbacks 
boundaries
             // Crash immediately
             exit(-1);
             return 0; // <--HERE WARMING
         }

It is worked! Thank!
