<p>
It is not yet possible to use <code class="computeroutput"><span class="identifier">typeinfo</span></code>
for float_128 on GCC: see <a href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43622" target="_top">GCC
43622</a>
</p>
<p>
so this fails to link <code class="computeroutput"><span class="identifier">undefined</span>
<span class="identifier">reference</span> <span class="identifier">to</span>
<span class="identifier">typeinfo</span> <span class="keyword">for</span>

<p>
This prevent using the existing tests for Boost.Math distributions, (unless
a few lines are commented out) and if a MACRO BOOST_MATH_INSTRUMENT controlling
them is defined then some diagnostic displays in Boost.Math will not work.
</p>
<p>
However this is only used for display purposes and can be commented out until
this is fixed.
