--- Comment #10 from Martin Liška <marxin at gcc dot gnu.org> ---
I spent quite some time with that and it's much complicated. Basic problem I
face is that there are 2 situations:
1) -Wno-error=pedantic - in that situation -Wpedantic should not be set
(because it's not enabled before)
2) -Werror -Wno-error=implicit - here -Wimplicit should be set + all
sub-options
So it definitely needs to go through handle_generate_option:

which implements EnabledBy dependencies. I'm retreating for now :/
