Subject: [PULL 1/8] configure: Use -std=gnu11
Date: Tue, 15 Jun 2021 18:36:22 -0700	[thread overview]
Message-ID: <20210616013629.1458790-2-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210616013629.1458790-1-richard.henderson@linaro.org>

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.
