Is interval arithmetic supported on x86 platform, Solaris 10?

I have installed Solaris 10 on my machine, which has an Intel Pentium 4 processor. I have installed Sun Studio 10 as well.

There is no suninterval.h on the hard drive. I looked at the CC flags, there is not any -xia flag listed in the output of CC -help.

Is interval arithmetic supported on x86 platform? Or what is wrong?

Thanks in advance!

Interval arithmetic is not yet available on x86/x64. We plan to have it in the next release. Watch for announcements of future releases of Sun Studio Express, the preview of the next release. http://developers.sun.com/prodtech/cc/downloads/express.jsp
