From ffe3e478657dc7126fca6329dfcedc49f4c726d9 Mon Sep 17 00:00:00 2001 From: Lars Volker Date: Wed, 10 May 2017 22:50:32 +0200 Subject: Only use O_CLOEXEC on platforms that support it Change a9fca58 made use of the O_CLOEXEC flag, which is not supported on older Linux kernels. This change makes the use contingent on kernel support. Testing: I manually compiled breakpad on CentOS 5.8 running kernel 2.6.18-308.8.2.el5.centos.plusxen.
