Add IPV6_FLOWINFO and IF_NAMESIZE values into generated package
System.OS_Constants.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* gsocket.h: Include net/if.h to get IF_NAMESIZE constant.
* s-oscons-tmplt.c: Define IPV6_FLOWINFO for Linux.diff --git a/gcc/ada/gsocket.h b/gcc/ada/gsocket.h
