Does this look right?

Yes. Looks like another thing coming from Solaris having a non-optimal
literal value for e (exp(1), decimal floating point literals, etc.). I'd
much rather fix the underlying issue, but I wouldn't know where to start.

There is another maths library which can be linked, rather than using -lm. That
at least got around this for the previous case of this.
But I don't think that is going to be very practical in Sage - too much is
hard-coded. I think for now, we will just have to put up with a slightly less
accurate result.
Ultimately, the FPU uses 64-bit, whereas that in the Intel chip works to 80-bits
internally, but 64-bit when the data is read out. I think inherently the SPARC
chip is less accurate.
