Well, without them things aren't perfect. But providing smalls as
double-precision floating-point is pretty good. And likewise with named
numbers. And it saves debuggers from having to support abitrary-length
integers. But I certainly wouldn't object to a new DW_TAG_rational_constant
that provided perfect representations.

Yes and no. I have permission to distibute Concurrent's, but it isn't
anywhere that's easy to reach at the moment. I'll send you a copy in a
subsequent email (to keep the mailing list bandwidth low).
Michael Eager is planning to place DDC-I's spec on the Dwarf 3 website. And
I'll be sending him a copy of Concurrent's spec to go in the same place.
