Review Comment:
   The original code looks like this:
   
   ```
           } else if (expected < 1) {
               if (checker instanceof ForkedCompiler) {
                   return true; // That implementation actually knows nothing 
about which options are supported.
               }
               warning = "The '" + option + "' option is not supported.";
           } else if (expected == 0) {
               warning = "The '" + option + "' option does not expect any 
argument.";
           } 
   ```
   
   So if expected == 0 do we still need to check if checker instanceof 
ForkedCompiler?
