+<p>It has been found that the GCC 3.3.3 compiler provided with recent Cygwin
+versions is incapable of compiling the LLVM CFE correctly. If your Cygwin
+installation includes GCC 3.3.3 we <i>strongly</i> recommend that you download
+GCC 3.4.3, build it separately, and use it for compiling LLVM CFE. This has been
+shown to work correctly.</p>
