question about compiling with g++ 3.1 version

[Janos Murvai]

Dear gcc users,

I tried to compile one program that is compilable with g++ 2.95.3
version..

The is problem with these lines:

class VectorMultiset {
  typedef vector< multiset<unsigned long>* >::iterator VSI;
  typedef vector< multiset<unsigned long>* >::const_iterator CVSI;
 ....

I got error message:

In file included from vertices.h:6,
                 from coalescent.h:13,
                 from Coalescent7.cc:5:
vectormultiset.h:13: ISO C++ forbids declaration of `vector' with no type
vectormultiset.h:13: template-id `vector<std::multiset<long unsigned int,
   std::less<long unsigned int>, std::allocator<long unsigned int> >*>'
used as
   a declarator
vectormultiset.h:13: parse error before `::' token
vectormultiset.h:14: non-template type `vector' used as a template
vectormultiset.h:14: ISO C++ forbids declaration of `const_iterator' with
no
   type
vectormultiset.h:14: confused by earlier errors, bailing out
Exit 1

How I can do vector< multiset<unsigned long>* > in g++ 3.1 version?
