There's a new version at
http://common-lisp.net/~rtoy/qd-2007-06-14.zip. 

Mostly bug fixes and better handling of signed zeroes, infinities, and
NaN's.  One user visible change is that #q() for reading complex
quad-doubles needs to be written #q(#q1.1 #q2.2) to get the components
read in as quad-doubles.  #q(1.1 1.2) reads 1.1 and 2.2 as
single-floats and converts them to quad-doubles.

Other than bug fixes, I'm basically done and don't have any plans to
really do much with this.  I didn't have an application in mind anyway
for this, so it was just a side project.
