Subject: include: Switch from __unused to new LIBBSD_UNUSED
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=abe3c8c33289e15e235aff120399ede316270a52;p=thirdparty%2Flibbsd.git

include: Switch from __unused to new LIBBSD_UNUSED

Because we do not define __unused, as on GNU systems Linux and glibc
providing conflicting symbols, declarations for imported functions that
use that attribute cause build failures when used.

Ref: https://bugs.debian.org/1083196
Fixes: #34
