11d50ecb9f Replacing the use of <iomanip> with <boost/detail/iomanip.hpp> across Boost.
On Linux, GNU's libstdc++, which is the default stdlib for icc and clang,
cannot parse the <iomanip> header in version 4.5+ (which thankfully neither
compiler advises the use of yet), as it's original C++98-friendly
implementation has been replaced with a gnu++0x implementation.
<boost/detail/iomanip.hpp> is a portable implementation of <iomanip>, providing
boost::detail::setfill, boost::detail::setbase, boost::detail::setw,
boost::detail::setprecision, boost::detail::setiosflags and
boost::detail::resetiosflags.

With respect to function templates, <TT>enable_if</TT> can be used in multiple different ways: The <TT>enable_if</TT> template can be used either as the return type, or as an

<H3><A NAME="htoc7">3.1</A>&nbsp;&nbsp;Enabling function templates in C++0x</H3><!--SEC END -->
In a compiler which supports C++0x default arguments for function template parameters, you can
enable and disable function templates by adding an additional template parameter. This approach
works in all situations where you would use either the return type form of <TT>enable_if</TT> or
the function parameter form, including operators, constructors, variadic function templates, and
even overloaded conversion operations.
As an example:

#include &lt;boost/utility/enable_if.hpp&gt;
