There is a bug in the logic of the autogenerated code:
if (!opts_set->x_warn_unused_parameter && (opts->x_warn_unused &&
opts->x_extra_warnings))
handle_generated_option (opts, opts_set,
OPT_Wunused_parameter, NULL, value,
lang_mask, kind, loc, handlers, dc);
When processing -Wno-unused, opts->x_warn_unused is false, so we don't turn off
OPT_Wunused_parameter. I think the generated code should be:
if (!opts_set->x_warn_unused_parameter && opts->x_extra_warnings)
for case OPT_Wunused and
if (!opts_set->x_warn_unused_parameter && opts->x_warn_unused)
for the case OPT_Wextra. So optc-gen.awk needs adjusting. Let me see if I can
find time to do this in the coming weeks/months, but if anyone wants to
investigate how to fix it, please go ahead.
I think this is a different bug than the -Wno-tabs, since that is not handled
by the autogenerated code.

--- Comment #6 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
I created bug 52347 to track the autogenerated code issue. This bug should be
fixed if Fortran's -Wall is moved to the autogenerated method of handling group
options (see options.texi)

--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
There seems to be more issues in the raw string literal lexing. E.g.
const char *s = R"a??/(x)a??/";
should be I think handled the same as
const char *s = "x";
with -std=c++11 or -std=gnu++11 -trigraphs, but is not. We only revert the
phase 1 and phase 2 transformations in between ( and ), but they should
actually be reverted everywhere between the " after R and the final ".
