Templated constructors.
<p>
Unfortunately, some systems which fail to properly support partial function template
ordering cannot support the concept of a templated constructor as implemented above.  
A special"wrapper"  macro has been created to work around this problem. With this "wrapper" 
the above example is modified to:
<pre><code>
std::copy(
    base64_text(BOOST_MAKE_PFTO_WRAPPER(address)),
    base64_text(BOOST_MAKE_PFTO_WRAPPER(address + count)),
    ostream_iterator&lt;char&gt;(os)
);
</code><
