<h2>Portability</h2><a name="Portability" ></a>
<p>
A huge effort has been made to port the library to as many compilers as possible.
<!-- The results of the test-suites can be found <a
href="http://boost.sourceforge.net/regression-logs/developer/range.html">here</a
>.--> </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.
</p>
<p >
Notice also that some compilers cannot do function template ordering properly.
In that case one must rely of <a
href="boost_range.html#range_result_iterator"><code >range_result_iterator</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:
<ol>
<li>
do not use built-in arrays,
<li>
do not pass rvalues to <a
href="boost_range.html#begin"><code>begin()</code></a>, <a
href="boost_range.html#end"><code>end()</code></a> and <a href="utility_class.html#iter_range">
<code>iterator_range</code></a> Range constructors and assignment operators,
<li>
use <a href="boost_range.html#const_begin"><code>const_begin()</code></a>
and <a href="boost_range.html#const_begin"><code>const_end()</code></a>
whenever your code by intention is read-only; this will also solve
most rvalue problems,
<li>
do not rely on ADL:
<ul>
<li>
if you overload functions, include that header <i>before</i> the headers in this
library,
<li>
put all overloads in namespace <code>boost</code>.
</ul>
</ol>
