Re: float8 regression test failure in head

Attached is a patch for this issue. I've checked with Chris, and this
patch allows the regression tests to pass on his machine. I also
updated float8-exp-three-digits expected file, but I wasn't able to
test these changes (I don't have access to a QNX machine).

I intend to apply this patch tomorrow.

Cheers,

Neil
