They're both right.  setgid is specified by POSIX, but Linux only
follows the exact details of that specification if you explicitly ask
for that (see the text of their man page).  By default, it follows
"System V" semantics.

DJGPP implements POSIX behaviour (but usually fails the call, as if
you were on a system were only one group was defined at all).

SVID is "System V Interface Definition" or something equivalent, IIRC.
