From 8a0afbb2a4f7da5e6a542787ea90eb240e7ac65d Mon Sep 17 00:00:00 2001 From: Stefan Weil Date: Wed, 2 Nov 2022 21:22:58 +0100 Subject: Fix broken configure with -Wunused-parameter The configure script fails because it tries to compile small C programs with a main function which is declared with arguments argc and argv although those arguments are unused. Running `configure -extra-cflags=-Wunused-parameter` triggers the problem. configure for a native build does abort but shows the error in config.log. A cross build configure for Windows with Debian stable aborts with an error. Avoiding unused arguments fixes this.
