From 82387db20e8a22475a242705795d451219167ceb Mon Sep 17 00:00:00 2001 From: "A. Wilcox" Date: Fri, 2 Dec 2016 01:27:14 -0600 Subject: [PATCH] KDECompilerSettings: Ensure POSIX correctness This change ensures that _XOPEN_SOURCE is defined. Since we use -std= iso9899:1990, GCC and Clang won't enable this definition by default. On non-glibc systems (where _GNU_SOURCE isn't defined), this causes most POSIX interfaces to be missing, which cause various build failures. Signed-off-by: A.
