[PATCH 1/2] Add braces in initializers for GCC 4.9 or older

[H.J. Lu]

Add braces to silence GCC 4.9 or older:

getaddrinfo.c: In function ‘gaih_inet’:
getaddrinfo.c:1135:24: error: missing braces around initializer [-Werror=missing
-braces]
       / sizeof (struct gaih_typeproto)] = {0};
                        ^
