Hi,

Please compile the attached source. Compilation will fail on both Solaris 8:

$ g++ --version
g++ (GCC) 3.3.2
[...]
$ g++ -c foo.cc
foo.cc: In function `int main()':
foo.cc:8: error: no match for 'operator!=' in 'i != std::vector<_Tp,
   _Alloc>::rbegin() [with _Tp = int, _Alloc = std::allocator<int>]()'
$ 

and Red Hat Linux 9:

$ g++ --version
g++ (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
[...]
$ g++ -c foo.cc
foo.cc: In function `int main()':
foo.cc:8: no match for `
   std::reverse_iterator<__gnu_cxx::__normal_iterator<const int*,
   std::vector<int, std::allocator<int> > > >& !=
   std::reverse_iterator<__gnu_cxx::__normal_iterator<int*, std::vector<int,
   std::allocator<int> > > >' operator
