checking portability:
        Solaris 10 returns ERR
        IRIX64     returns ERR
        HPUX 11.23 returns OK
        Tru64      returns ERR
        AIX    6.1 returns OK

Though HPUX implemented SVr4, it was the last (and some of its differences from 
the
other systems demonstrate that the implementers relied more on documentation 
than
on cross-checking).  Tru64 is technically the best of the above listed; Solaris
has a lot of code rot.  So I've found no reason to change the quirk.
