    This is hardly newsworthy. If the extensions were called ‘Jabberwocky C Extennsions’ no one would have cared. The extension allows for tagged unnamed structs inside of a struct, e.g.:

    struct inner { /* ... */ };
struct outer {
    int value;
    struct inner;
};

        Tag is what goes after the struct keyword to allow referring to the struct type. Structs don’t have to have a tag. Name is what field are called. Adapting Obin’s example:

        struct foo { int baz; };
struct bar { struct foo qux; };
struct bar data;
data.foo.baz = 0;

        foo and bar are tags for struct foo and struct bar types respectively. And baz and qux are field names.
