On i386 with optimization you get a few extra bits of precision
because gcc holds values in the 8087 registers. Without optimization
it writes back to memory after every op, forcing rounding at each
stage.
(Unoptimized is still not always the same as an actual 53-bit chip
like ppc, since there's two roundings, first to 64 bits then to 53.)
