Hi,
the following patch adds fix-it hints to the C++ parser for two wrongly
used keywords detected in cp_parser_decl_specifier_seq.
Bootstrapped and regtested on x86_64-pc-linux-gnu.
OK for trunk?
Regards,

What caught my eye here is the "please remove it" part :) Maybe
it's me but it seems a little too forceful for a warning (despite
the please). I would find a more conventional phrasing like
"suggest to remove it" to be more suitable.
That said, I wonder if removing the auto is actually the best
suggestion. Wouldn't it more in line with where C++ is headed
to suggest to remove the type and keep the auto?
