Heh, that change came from my noticing that the text misspelled HP's 
name; there should have been a hyphen between "Hewlett" and "Packard". 
And then when I looked into what the passage was about, it appeared that 
the circa-1980 HP work was long-dead. At least, I couldn't find mention 
of it in the most recent HP-UX manual I could find 
<http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-c01921592-1.pdf>. So 
that's why I replaced its mention with a pointer to Hinnant's recent work.

If the HP API is still actively used and there's a URL for it, we can 
certainly put it back in.
