Subject: [PATCH bpf-next v1 1/6] bpftool: Compile using -std=gnu89
Date: Sat, 6 Nov 2021 05:12:38 +0530 [thread overview]
Message-ID: <20211105234243.390179-2-memxor@gmail.com> (raw)
In-Reply-To: <20211105234243.390179-1-memxor@gmail.com>
The minimum supported C standard version is C89, with use of GNU
extensions, hence make sure to catch any instances that would break
the build for this mode by passing -std=gnu89.
