-pedantic -> type is no longer a type in 19990131

[Leo Breebaart <leo at lspace dot org>]

A file containing nothing but the following code:

---------------------------------------------------------------------------
#include <vector>

using std::vector;

template <class T>
class TPVector : public vector<T *>
{
    typedef vector<int *>::const_iterator iptype;
    typedef vector<T *>::const_iterator tptype;
};
---------------------------------------------------------------------------

compiles cleanly with both egcs 1.1.1 and the 19990131 snapshot (and
subsequent code does exactly what you'd expect).

However, if I compile with -pedantic on, I get told for the second typedef:


    warning: ANSI C++ forbids typedef which does not specify a type
    cannot declare member `vector<T *,__default_alloc_template<true,0> >::const_iterator' within `TPVector<T>'
    parse error before `;'


I am at a complete loss as to why 'vector<T *>::const_iterator' should,
within this context, not be considered a type, even if only pedantically.
Surely, within the scope of the template parameter T, the second typedef
should be no different from the first typedef?

Consequently, I am submitting this as a possible compiler problem -- I
apologise beforehand if the problem is with my lack of understanding of C++
or templates instead, in which case I would be most grateful for
enlightenment in e-mail.

Cheers,
