Subject: [PATCH] accessibility/speakup/speakup_acnt: Add header file macro definition
Date:   Tue,  5 Jul 2022 18:19:55 +0800
Message-Id: <20220705101955.27337-1-zeming@nfschina.com>
Precedence: bulk

I think the header file could avoid redefinition errors.
 at compile time by adding macro definitions.
