From 8cda82b726349b8f0a719a9945541e253b3f2118 Mon Sep 17 00:00:00 2001 From: Chengwei Yang Date: Fri, 28 Jun 2013 20:26:28 +0800 Subject: [PATCH] cmake: do not bind to any particular POSIX C standard This caused build failures on FreeBSD. Defining _POSIX_C_SOURCE to a particular version will disable common non-POSIX extensions like PF_UNIX, and on some systems will also disable features of later POSIX versions, like IPv6. If we don't ask for a specific version, we'll get some sort of sensible default.
