Yeah, the first field of the semid_ds-structure is also a structure (at least
on Linux and FreeBSD), so using two layers of braces should work:
struct semid_ds buf = {{ 0 }};
If that's not portable enough, then bzero() might be in order:
bzero(&buf, sizeof(buf));
however annoying it might be to have a function-call (even if compiler will
optimize it away) just to zero-out an automatic variable :-(
