Tests pass for me on all the implementations I have on Mac OS X
(Yosemite), linux, and Windows.
Now running the upgrade tests on linux on CCL, SBCL, CMUCL, Allegro,
lispworks, ECL, ECL bytecodes, and MKCL.
If those pass, I will bless the current head as 3.1.6.
The upgrade tests are very time consuming, so I'll check in on them
tomorrow morning.
