  29 the unrolling depth of the library's iteration algorithms. In this implementation
  30 of the library, <tt class="literal"><span class="pre"><a href="./limit-unrolling.html" class="identifier">BOOST_MPL_LIMIT_UNROLLING</a></span></tt> has a default value of 4. To

  32 value before including any library header.
  33 [<em>Note:</em> Overriding will take effect
  34 <em>only</em> if the library is configured not to use <a class="reference internal" href="./cfg-no-preprocessed-headers.html#boost-mpl-cfg-no-preprocessed">preprocessed headers</a>. See
