 Toolkit Compiler. This provides a way of building Python using freely
 available software.
 
+Note that Microsoft have withdrawn the free MS Toolkit Compiler, so this can
+no longer be considered a supported option. The instructions are still
+correct, but you need to already have a copy of the compiler in order to use
+them. Microsoft now supply Visual C++ 2005 Express Edition for free, but this
+is NOT compatible with Visual C++ 7.1 (it uses a different C runtime), and so
+cannot be used to build a version of Python compatible with the standard
+python.org build. If you are interested in using Visual C++ 2005 Express
+Edition, however, you should look at the PCBuild8 directory.
