Note that in 4.7 all options will be validated by the .opt machinery 
(producing "gcc: error: unrecognized command line option '---'") by the 
driver and only options passing that (and -Wno-* options) will then go 
through the specs validation as well.  This may break things depending on 
the exact error message; it may also make this bug less significant 
because fewer cases will be left to be caught by the check against specs.
