+      DragonEgg release.  It requires

+      <a href="http://gcc.gnu.org/gcc-4.5/">gcc-4.5</a>.</p>
+      <p>The 2.9 release has the following notable changes:</p>
+      <ul>
+      <li>The plugin is much more stable when compiling Fortran.</li>
+      <li>Inline assembly where an asm output is tied to an input of a different
+      size is now supported in many more cases.</li>
+      <li>Basic support for the __float128 type was added.  It is now possible
+      to generate LLVM IR from programs using __float128 but code generation
+      does not work yet.</li>
+      <li>Compiling Java programs no longer systematically crashes the
+      plugin.</li>
+      </ul>
+      <p>Common problems with building the DragonEgg-2.9 release:</p>
+      <ul>
+      <li>If you had to install the GMP, MPC or MPFR libraries locally in order
+      to build gcc-4.5, then the dragonegg build may fail due to not finding
+      header files from the libraries.  You can tell the dragonegg build
+      system where to find them by setting CPPFLAGS before calling make:
+      <pre>
+        CPPFLAGS="-I/path/to/header/files -I/another/header/path/" make
+      </pre>
+      </li>
+      <li>
+      The build fails if you are using a case insensitive file system.
