Subject: configure.ac: Fix -Wstrict-prototypes
X-Git-Tag: V_9_2_P1~141
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=12af712d116f42164bcfa56db901d06e4fa27199;p=thirdparty%2Fopenssh-portable.git

configure.ac: Fix -Wstrict-prototypes

Clang 16 now warns on this and it'll be removed in C23, so let's
just be future proof. It also reduces noise when doing general
Clang 16 porting work (which is a big job as it is).  github PR#355.
