I think this is because warning() is a parse-time operation and not a run-time operation. This means that if the file contains a warning anywhere (and that is not excluded because of an ifdef statement), it gets added to the list of warnings that is displayed at program end. This happen regardless of whether or not the warning() is in the execution path.

If you need to provide a run-time message, then you still do that the traditional way.

export function eqtQuadIntToSequence(integer count, atom ptr)  
  if (count < 1) or (count > 4) then  
    printf(2, "WARNING: eqtQuadIntToSequence(%d,%g): Parameter \"count\" out of range.", {count,ptr})  
    if count < 1 then  
      count = 1  
    else  
      count = 4  
    end if  
  end if  
  return peek4u({ptr, count})  
end function
