Subject: [PATCH 2/2] use the correct attributes for ___errno_location
Date: Sat, 29 Jun 2019 16:22:44 -0500	[thread overview]
Message-ID: <20190629212244.42963-3-samuel@sholland.org> (raw)
In-Reply-To: <20190629212244.42963-1-samuel@sholland.org>

In the public header, __errno_location is declared with the "const"
attribute, conditional on __GNUC__. Ensure that its internal alias has
the same attributes.
