struct structTag {
    int i;
};

struct structTag foo;

struct {
    int i;
} structVar;

struct structTag2 {
    int i;
} structVar2;

typedef struct structTag2 foo_t;
foo_t bar;

These all are working structures:

int main() /* useless -only check on derefence */
{
    printf("foo.i = %d\n", foo.i);
    printf("structVar.i = %d\n", structVar.i);
    printf("bar.i = %d\n", bar.i);
    return 0;
}

So there should be another reason. Maybee a question to *.comp.lang.c
