Ditto here on BSD.  It compiled okay with the addition of another level of
matching {}:

stuff[20][30] = {
     {
        {"joe", 1, 0, 12},
        {"fred", 1, 0, 13},
        {"carol",1, 0, 4} }
     }

K&R p. 124 says, for a particular example, "... It would be more precise
to enclose initilizers for each 'row' or structure in braces, ... but the
inner braces are not necessary when the initializers are simple variables
or character strings, and when all are present."

Apparently some compilers prefer the inner braces. It doesn't hurt to have
them in either case.
