Subject: Re: [PATCH v4 18/28] reftable: implement stack, a mutable database of reftable files.

From: Junio C Hamano <[email-masked]>
Date: Thu, 26 Aug 2021 22:33:35 -0700

This step does not compile under -pedantic because it assumes that
__FUNCTION__ is available unconditionally (unlike trace.h where it
allows __FUNCTION__ to be used iff compiler supports it).

Here is a workaround that needs to be split and squashed into the
steps that introduce these test source files.

Subject: [PATCH] SQUASH???
