On MacOS X it is now possible to install the framework in 64-bit mode or
even as a 4-way universal binary (that is, PPC, i386, PPC64 and x86_64
support in one binary).

This is controlled by the configure argument ``--with-universal-archs``:

- ``--with-universal-archs=all``: install 4-way universal

- ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the
default)

- ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

This option should be used in combination with ``--enable-universalsdk=``.

NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or
later).
