From 253561cfcc3b95d21046bf08467fa0f68be385da Mon Sep 17 00:00:00 2001 From: Alan Coopersmith Date: Mon, 21 Nov 2022 11:33:26 -0800 Subject: Wrap XComposite*CheckExtension() in do { ... } while(0) Makes macro expansion safer and eliminates -Wextra-semi-stmt warnings from clang every time it is called due to semicolon after bracket.
