Subject: [PATCH 3/3] add builtin types for size_t*, intmax_t* & ptrdiff_t*
Date: Sun,  4 Oct 2020 13:43:49 +0200
Message-ID: <20201004114349.81440-4-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <20201004114349.81440-1-luc.vanoostenryck@gmail.com>

This is needed for printf format checking of "%zn", "%jn" & "%tn".
