From dc38852aaa4ac187d8b44201f75fc2835241912d Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Sat, 7 May 2016 21:16:42 -0600 Subject: [PATCH] qemu-io: Use bool for command line flags We require a C99 compiler; let's use it to express what we really mean. (Yes, we now have an instance of 'if (bool + bool + bool > 1)', which, although semantically valid C, looks ugly; it gets cleaned up later.)
