Subject: build: allow more modern coding style with empty initializers
X-Git-Tag: 0.7.0~40
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d56bb3bd6cf8f501ce23dc50ee53dc573c9253a0;p=thirdparty%2Flldpd.git

build: allow more modern coding style with empty initializers

In C99, we can do:

     struct ifreq ifr = {};

Instead of

     struct ifreq ifr;
     memset(&ifr, 0. sizeof(ifr));

We disable the empty initializer warning to allow this. Moreover, we
also allow to mix code and declarations.
