Some places.  You have to label the outlets "NO EQUIPMENT GROUND" and
"GFCI protected".  (I've never seen any labeled, until a couple months
ago, when an inspector pointed this out (and refused to sign off on)
in a building a client uses.)  It's more complicated than this, I
think, too.  (It may be that if you're providing ground plugs other
than at the GFCI, you need ground between the GFCI and the new plugs)
Check your local code!
