#include <sys/socket.h> with -D_GNU_SOURCE fails to build with clang

[cmorve-te]

If you take this program

#include <sys/socket.h>
void test(){}

which builds with no issues with clang -O1 -D_GNU_SOURCE -o /dev/null -c test.c.

And use OpenOSC 1.0.7, it fails with

$ clang -O1 -D_GNU_SOURCE -o /dev/null -c test.c -include /usr/include/openosc.h 
In file included from test.c:1:

This seems to happen because glibc uses a special sockaddr definition: https://sourceware.org/git/?p=glibc.git;a=blob;f=socket/sys/socket.h;h=e72f5e722e4cd6ca5e04fe05b94dcf2963c3b124;hb=HEAD#l80
