From d22797ce36a388214dfc03b49d3609a334a52ff7 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Mon, 14 Jun 2021 16:31:36 -0700 Subject: [PATCH] configure: Use -std=gnu11 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Now that the minimum gcc version is 7.5, we can use C11. This will allow lots of cleanups to the code, currently hidden behind macros in include/qemu/compiler.h.
