I'm more interested in the source code side; as I understand it, g++ <file>
will fail if we test __sparc__ and try to use cas. Do you think that
#if defined( __sparc_v8__ ) || defined( __sparc_v9__ )
will work reliably (by which I mean, include the header file when it would
compile, and not include it when its compilation would fail)?
