How very odd.  When I tried it on SunOS, I got EINVAL.  I guess we need
to break it down by release - my test was under a "SunOS Release 4.1.2"

All you need to do is think of off_t as an unsigned type, and suddenly
there is no "before the begin[ning] of a file", only very large offsets
into a file. :-)

But I suppose that isn't very useful, because then L_INCR and L_XTND
can't take negative arguments. :-(
