Options are defined using .opt files. The set of such files used is determined through extra_options in config.gcc. You could readily have determined this for yourself by grepping for option names present in *_SWITCHES in older versions and seeing where they now appear, or by reading the internals manual which has a chapter "Option specification files". -- Joseph S.
