Subject: [PATCH 2/2] dtc: ensure that command line options arrays length match
Date: Sun,  3 Sep 2023 19:00:58 -0700	[thread overview]
Message-ID: <20230904020058.1935334-2-charles.perry@savoirfairelinux.com> (raw)

usage_long_opts and usage_opts_help should always have the same length.
Since these are fixed length arrays, this can be checked at compile time
with _Static_assert (requires C11).
