If exp is only 64 bits, there is ZERO value in supporting 80-bit reals. None at
all. If tests are only failing because of low exp() precision, they deserve to
fail. I would say that DMD's implementation of 80-bit exp and transcendentals
is as inaccurate as you could possibly allow. Probably too inaccurate. If
anything does worse than it, it's really, really bad.

OTOH we will need 64-bit function results, for machines where real == double.
