Well, I think it's an instance of the variable sized array extension.
You just have a pointer there, as far as I understand it. The memory is
allocated in a different location at runtime. So there should be no
problem to compute sizeof().
Btw, all versions since 3.0 accept the code - and since 3.3.1 they
reject it if -pedantic is specified.
