Hi,

Whenever sage_fortran builds an executable on my Open Solaris system, it is
doing so as 32-bit. As far as I am aware, the problems with other packages
building 32-bit objects have all been resolved or can be worked around by
setting environment variables (like CFLAGS=-m64, CXXFLAGS=-m64 etc).

I think they needed about 7.2 TB of disk space.
It would be possible to adapt the theta code we used for the trillion
triangles problem to do this computation. But it would be a massive
job. At present there is only multiplication, let alone square root.
