[vtkusers] Fwd: Volume Rendering with multiple-array data

[Randall Hand]

Ok, we just upgraded GCC to the latest SGI-published version.

[1024] [rhand at prism:~/src/offscreen-raycast]                          
                           [10:34:28am]% gcc -v
Reading specs from /usr/freeware/lib/gcc-lib/mips-sgi-irix6.5/3.3/specs
Configured with: ../configure --prefix=/usr/freeware
--enable-version-specific-runtime-libs --disable-shared
--enable-threads --enable-haifa --enable-libgcj --disable-c-mbchar
Thread model: single
gcc version 3.3

                           [10:34:29am]%

You can see --enable-threads, but "Thread model:single" is still
there.  RayCast'ing still crashes with >1 threads enabled.

The admins are currently downloading source for the latest 3.4
release, and will have that installed in a little while. I'll let ya
know how that goes.
