From 4bfbc355de9d47b2b67e9b7c71ec6fb08fd5ab53 Mon Sep 17 00:00:00 2001 From: Sascha Grunert Date: Fri, 21 Jun 2019 10:14:19 +0200 Subject: Build cgo files with -Wall -Werror To avoid unnecessary warnings and errors in the future I'd like to propose building all cgo related sources with `-Wall -Werror`. This commit fixes some warnings which came up in `shm_lock.c`, too.
