Yea, that's weird.

Yea. gcc 4.6.0 is pretty ridiculous - the only thing we gain by testing with a
.0 compiler of that vintage is pain. Could it be upgraded?

TBH, I think we should just desupport HPUX. It's makework to support it at
this point. 11.31 v3 is about to be old enough to drink in quite a few
countries...
