[PATCH 0/2] C99: harder dependency on variadic macros

Since [1] which has been out since v2.31.0 we've had a hard dependency on variadic macros.

Removing the relevant always-off-unless-you-monkeypatch-the-source code may be too aggressive for Junio's "Let's give it enough time"[2].

But I'm submitting this because of brian m. carlson's note[3] about wanting to submit more general patches for declaring a hard dependency on all of C99.

Whatever anyone thinks of that this harder dependency on C99 variadic macros would be a subset of such a change, so it makes sense to consider it first. Let's see if anyone has an issue with this landing before brian's suggested larger change.
