--- Comment #8 from Kai Tietz <ktietz at gcc dot gnu.org> --- please note that bugzilla isn't the proper place to get end-user support about how to use options. To cite your favorite sentence "please read first the mail-archive". Actually you weren't the first person having this question. Such questions are better placed at gcc-help.
