hi -

I included a little patch with the previous regression report i sent;
however, that was a little cheesy in that it tested for just __alpha.
Here's one which might be a little more generally applicable.
This still assumes that a double is 64 bits, but i'm not sure how
to reliably test for that using the preprocessor.
