I don't want to enable them. The problem is not with too little but too many
warnings.

A snippet from one of the problematic files:

        { NULL, NULL, false, false }

is preprocessed to 

 { 
# 62 "AdsPlugin.cpp" 3 4
  __null
# 62 "AdsPlugin.cpp"
      , 
# 62 "AdsPlugin.cpp" 3 4
        __null
# 62 "AdsPlugin.cpp"
            , false, false }
};

Here I see the same flags, yet for these two NULLs gcc warns.
