From d5c0351055d5709da8f3e16c91348092fdb481aa Mon Sep 17 00:00:00 2001 From: Marcel Raad Date: Mon, 9 Jul 2018 18:38:23 +0200 Subject: configure: conditionally enable pedantic-errors Enable pedantic-errors for GCC >= 5 with --enable-werror. Before GCC 5, pedantic-errors was synonymous to -Werror=pedantic [0], which is still the case for clang [1]. With GCC 5, it became complementary [2]. Also fix a resulting error in acinclude.m4 as main's return type was missing, which is illegal in C99.
