I think some work is still needed on the diagnostic wording.

"a ISO C" is not proper usage. I think something like "by ISO C before
C99" would be better. Likewise "a ISO C++".
"!flag_isoc99" is more usual than "flag_isoc99 == 0".

"a GNU extension" suggests a particular language feature, but I think
you're actually referring here to a whole language version rather than an
individual feature.
In any case, -std=gnu89 supports flexible array members. So I'd expect
them to have exactly the same semantics as in C99, so disallowing a
particular feature for gnu89 here seems suspect.
In the manual, any literal code should be enclosed in @code{} or @samp{}.
That replaces the use of ASCII quotes "" that you currently have in the
documentation (that should never be used outside of @code, @samp and
similar).

And @option{} should be used around "-std=gnu89" here (except as noted
above, I think it's suspect to disallow parts of this feature for gnu89).

"FOR" should be "For".
