From 7deb7e6acd4fb8dd09c8e38eb2e07c86371bf94e Mon Sep 17 00:00:00 2001 From: James Almer Date: Fri, 13 Oct 2017 12:34:34 -0300 Subject: [PATCH] configure: force erroring out in check_disable_warning() if an option doesn't exists Should prevent some options from being added to cflags when they don't exist and the compiler only warns about it.
