64-bit sparc/gcc?

Forgive me, I'm sure this question is asked all the time...

The GMP 4.0 documentation implies 64-bit builds are possible on Solaris
2.8 sparcv9 using gcc.  However, gcc 3.0 documentation contradicts this.
What am I missing?  Thanks, additional info below should you need it.

Both gcc and binutils packages were from sunfreeware.
