Would it
be possible to remove them retroactively from the -std=gnu99 and
-std=gnu11 language variants (as well as -std=c99 and -std=c11), so that
they are rejected by default?

-Werror=implicit-int -Werror=implicit-function-declaration

I want the default changed.  (I thought this was sufficiently clear from
my message.)
I think it's worth revisiting as well, burying in -pedantic seems wrong given the kinds of failures we can see.
