Also missing -Wredundant-tags:

$ cat t.C && gcc -S -Wmismatched-tags -Wredundant-tags t.C
template <int> class C { };

typedef C<0> C0;           // okay
typedef class C<0> C0;     // missing -Wredundant-tags

typedef C<1> C1;           // okay
typedef struct C<1> C1;    // missing -Wmismatched-tags
