"= { 0 }" _will_ init all fields to zero:
C99 Standard 6.7.8.21 : "If there are fewer initializers in a brace-enclosed
list than there are elements or members of an aggregate, or fewer characters in
a string literal used to initialize an array of known size than there are
elements in the array, the remainder of the aggregate shall be initialized
implicitly the same as objects that have static storage duration."
gcc's -Wmissing-field-initializers is overly noisy; good discussion here:
