You need -W. -W also notices the dangling elses, the intended code is this:

bool test(){
     static if(condA){
         static if(condB){
             static if(NEW_CONDITION) return true;
             else static if(condC){
                 if(funA()) return true;
             }else static if(condD) {
                 if(funB()) return true;
             }else{
                 if(funC()) return true;
             }
         }else static if(condD){
             if(funD()) return true;
         }else{
             if(funE()) return true;
         }
     }
     return false; // Warning: statement is not reachable
}

enum bool condA = true, condB = true, condC = true, condD = true;
enum NEW_CONDITION = true;
bool funA();
bool funB();
bool funC();
bool funD();
bool funE();
