-pedantic and typename

[Gerald Pfeifer]

I noticed that the current CVS snapshot generates a warning followed by
an error for the following

---------- snipedee-snip ----------
#include <vector.h>

template <class T>
class NAMESTABLE
    {
    typedef /*typename*/ vector<T>::iterator iterator;
    };
---------- snipedee-snip ----------

when -pedantic is used, but compiles fine without pedantic.

x.cc:6: warning: ANSI C++ forbids typedef which does not specify a type
x.cc:6: cannot declare member `vector<T,__default_alloc_template<false,0>
>::iterator' within `NAMESTABLE<T>'
x.cc:6: parse error before `;'


1) Is ``typename'' really required here?

2) Even if so, and the warning is okay -- why that error? 

3) According to gcc.info -pedantic only changes behavior according to
   ANSI C. Apparently, however, it also does something similar with
   regard to ISO C++. 

   Should the docs be updated in this direction?
