Topic: Class typedefs and C compat.

Hello all
I would like to know if the following incompatibility with C
is intended or not:
dcl.typedef and basic.lookup.elab in CD2 forbid the use of typedef
names following ``class'' and similar keywords. This means that
the following is ill-formed:
struct S {};
typedef struct S T;
struct T x; // illegal
The problem is the following C fragment
typedef struct S S;
struct S {...};
which I would say is perfectly legal ANSI C, and would be illegal
in C++ bacause the ``S'' in the struct definition is a typedef name...
