typo in pmc.h??

[Gopal Rajaraman]

There seems to be a typo in either pmc.h or parrotpointer.pmc

pmc.h has:
    PMC_private_GC_FLAG  = 2 << 12

but parrotpointer.pmc has
void init () {
      SELF->data=NULL;
      SELF->flags=PMC_private_gc_FLAG; ## you get a compile error at
this line....
   }

This causes the build to fail.
