Thats not true. cout<< test.size();
will work fine..
If resize is not a member(which btw my original STL documentation
does not mention too) then it would not be very difficult to use:
1)test.push_back(200);
2)test.insert(v.end,200);

Both will do what you want.

What remains is a design guestion. Why is pop_back in gcc implemented
as void??? Or put it another way: why not call it delete_back in that
case ??

Take care,

Rick
