<p>
A huge effort has been made to port the library to as many compilers as possible.
</p>
<p>
Full support for built-in arrays require that the compiler supports class template
partial specialization. For non-conforming compilers there might be a chance
that it works anyway thanks to workarounds in the type traits library. Visual
C++ 6/7.0 has a limited support for arrays: as long as the arrays are of built-in
type it should work.
</p>
<p>
Notice also that some compilers cannot do function template ordering properly.
In that case one must rely of <a class="link" href="reference/semantics/metafunctions.html" title="Metafunctions"><code class="computeroutput"><span class="identifier">range_iterator</span></code></a> and a single function
definition instead of overloaded versions for const and non-const arguments.
So if one cares about old compilers, one should not pass rvalues to the functions.
</p>
<p>
For maximum portability you should follow these guidelines:
</p>
<div class="orderedlist"><ol class="orderedlist" type="1">
<li class="listitem">
do not use built-in arrays,
</li>
<li class="listitem">
do not pass rvalues to <a class="link" href="reference/semantics/functions.html" title="Functions"><code class="computeroutput"><span class="identifier">begin</span></code></a><code class="computeroutput"><span class="special">()</span></code>,
<a class="link" href="reference/semantics/functions.html" title="Functions"><code class="computeroutput"><span class="identifier">end</span></code></a><code class="computeroutput"><span class="special">()</span></code> and <a class="link" href="utilities/iterator_range.html" title="Class iterator_range"><code class="computeroutput"><span class="identifier">iterator_range</span></code></a> Range constructors
and assignment operators,
</li>
<li class="listitem">
use <a class="link" href="reference/semantics/functions.html" title="Functions"><code class="computeroutput"><span class="identifier">const_begin</span></code></a><code class="computeroutput"><span class="special">()</span></code> and <a class="link" href="reference/semantics/functions.html" title="Functions"><code class="computeroutput"><span class="identifier">const_end</span></code></a><code class="computeroutput"><span class="special">()</span></code>
whenever your code by intention is read-only; this will also solve most rvalue
problems,
</li>
<li class="listitem">
do not rely on ADL:
<div class="itemizedlist"><ul class="itemizedlist" type="disc">
<li class="listitem">
if you overload functions, include that header before the headers in
this library,
</li>
<li class="listitem">
put all overloads in namespace boost.
</li>
</ul></div>
</li>
</ol></div>
