Which sounds like a bug in the wrapper to me (like the one that was just
fixed in the post coreutils 6.2 groups script).  If they really want to
stop parsing options, and pass all remaining arguments to gcc, then they
should be using -- between the options they give gcc and the remaining
arguments that they pass unchanged.  But as long as that bug in the
wrapper is still present, we might as well exploit it in depcomp :)
