It's certainly true.  I'm not sure about dn_GlobVec, but there are two specific
"nothing there" values possible for some BCPL-ish things.  Often a NULL pointer
in a field somewhere is taken to mean "I don't have my own THING, use the
default", whereas the 0xFFFFFFFF == -1L value is saying "don't use THING at
all".
