Subject: [PATCH] Add a blurb about using the GCC 3.4.3 compiler on Cygwin
(which works) for the CFE instead of the default GCC 3.3.3 compiler that
comes with Cygwin.

+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

+GCC 3.4.3, build it separately, and use it for compiling LLVM CFE. This has been
