for some reason the findfile does not work on the MinGW env

 std::string path = plug_path();
full_file_name = findfile(short_file_name, path, R_OK);
if (full_file_name != "") {
 // found it, with search
}else{untested();
 cmd.reset(here);
 throw Exception_CS("plugin findfile (" + short_file_name + " ) not found
in " + path, cmd);
}
      }

Will have to check later for options (note: maybe the exception should
mention findfile error as the branch is different from the . or / file
access)
