My version is: gcc (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609 I don't think that's really exocit version of the compiler, or is it? > Also tried using W=1 on the make command > line. Getting a bunck of other warnings, but not the ones above. This was without W=1, just a default compilation with all wireless drivers enabled. > Do you want me to fix it? Yes, please. I try to keep the patches warning free, even if they are false warnings. -- Kalle Valo
