30 There was a bug when using any quadmath <code class="computeroutput"><span class="identifier">expq</span></code>
31 function on GCC : <a href="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60349" target="_top">GCC
32 bug #60349</a> caused by <a href="http://sourceforge.net/p/mingw-w64/bugs/368/" target="_top">mingw-64
33 bug #368</a>.
34 </p>
35 <p>
36 To work round this defect, an alternative implementation of 128-bit exp was
37 temporarily provided by <code class="computeroutput"><span class="identifier">boost</span><span class="special">/</span><span class="identifier">cstdfloat</span><span class="special">.</span><span class="identifier">hpp</span></code>.
38 </p>
39 <p>
40 The mingw bug was fixed at 2014-03-12 and GCC 6.1.1 now works as expected.
