Subject: [PATCH 3/9] configurator: Inline err.h functions from musl libc
Date: Sun, 18 Sep 2016 18:52:00 -0600 [thread overview]
Message-ID: <d7b109044f3d73a3f91c56136ad487fe07b518a7.1474239353.git.kevin@kevinlocke.name> (raw)
In-Reply-To: <cover.1474239353.git.kevin@kevinlocke.name>
Since we can't use HAVE_ERR_H in configurator, provide a definition for
the err.h functions used. The version provided is the one from musl
libc, since it is concise and shares the MIT License with configurator.
