The way Sun's build environment supports 64-bit compilation, it is
only necessary to build all objects using -xarch=v9. The linker is
responsible for selecting the correct mode based on the mode of the
objects. All linked objects must be built for the same model or
linking will fail.

How is it that 64-bit was selected unless you requested it?
