  19 <p>It has always been a major goal of MPL development that a program
  20 using the MPL should compile and run without modification on a wide
  21 variety of compilers.  To this end, the library goes to great
  22 lengths to hide the quirks of less-than-perfect compilers. Of
  23 course, there is only that much that you can do about an utterly
  24 broken compiler.  This section describes the places where those
  25 quirks &quot;leak out&quot; of the library abstraction layer, and what you can
  26 do about it when they do.</p>
  27 <p>With respect to MPL compatibility we divide C++ compilers roughly
  28 into three categories:</p>
  29 <ol class="upperalpha simple">
  30 <li>Reasonably conforming compilers that &quot;just work&quot; with the MPL.</li>
  31 <li>Not-so-conforming compilers that work but require some workarounds in user code.</li>
  32 <li>Compilers that are so broken that it's not practical to use them for any serious
  33 metaprogramming work.</li>
  34 </ol>
  35 <p>We haven't tested every compiler in existence (simply because we don't have access to
  36 all of them), but chances are the table below
  37 will give you the information you are looking for. Please note that
  38 the fact that one version of a compiler appears
  39 in this list as &quot;Not supported&quot; does <em>not</em> mean that future versions are also
  40 unworkable — some vendors are working hard to correct the
  41 problems... and, as of this writing (late 2004), some are not.</p>
  42 <p>Please keep in mind that this is not a complete list!</p>
