  * Update the Mac/README file. Add the list of OSX-specific configure options
    to that README file with some explanation.
  
  * Be more strict in the configure script: complain loudly when the user has
    specified invalid combinations of OSX-specific configure arguments. 
    
    The error message refers to the Mac/README file for more information.

+The option ``--enable-universalsdk`` has an optional argument to specify an
+SDK, which defaults to the 10.4u SDK. When you build on OSX 10.5 or later

+2.1 Flavours of universal binaries
+..................................
+
+It is possible to build a number of flavours of the universal binary build,
+the default is a 32-bit only binary (i386 and ppc). The flavour can be
+specified using the option ``--with-universal-archs=VALUE``. The following
+values are available:
+
+  * ``32-bit``:   ``ppc``, ``i386``
+
+  * ``64-bit``:   ``ppc64``, ``x86_64``
+
+  * ``all``:      ``ppc``, ``ppc64``, ``i386``, ``x86_64``
+
+  * ``3-way``:	  ``ppc``, ``i386`` and ``x86_64``
+
+  * ``intel``:	  ``i386``, ``x86_64``
+
+To build a universal binary that includes a 64-bit architecture you must build
+on a system running OSX 10.5 or later. The ``all`` flavour can only be build on
+OSX 10.5.

-If you want to install some part, but not all, read the main Makefile. The
