How to use std::allocator in my own container class

I am trying to write a container class which uses STL allocators. What I currently do is to have a private member

std::allocator<T> alloc_;

(this will later be templated so that the user can pick a different allocator) and then call

T* ptr = alloc_.allocate(1,0);

to get a pointer to a newly allocated 'T' object (and used alloc_.construct to call the constructor; see the answer below). This works with the GNU C++ library.

However, with STLPort on Solaris, this fails to do the right thing and leads to all sorts of bizarre memory corruption errors. If I instead do

std::allocator_interface<std::allocator<T> > alloc_;

then it is all working as it should.

What is the correct way to use the stl::allocator? The STLPort/Solaris version fails to compile with g++, but is g++ right?
