commit 415ebc791e03780de0a40ea63234f223c1167614 Author: Sven Eckelmann sven@narfation.org Date: Fri Sep 23 16:35:57 2016 +0200
alfred: Enable _GNU_SOURCE by default
alfred uses any netlink library which is (more or less) compatible with libnl-3. This is for example libnl-tiny on OpenWrt.
Programs and libraries which are build against libnl-tiny must be build with _GNU_SOURCE enabled to have some types in its headers defined. Thus _GNU_SOURCE is enabled in the OpenWrt alfred package since 2016.3. But sometimes using _GNU_SOURCE and sometimes not using it can have severe side effects which are non-trivial to debug when the developer is not also using the same _GNU_SOURCE preprocessor define. Thus enable _GNU_SOURCE by default to have similar behavior (defines, type definitions, structure members, ...) from headers like on OpenWrt.
