Now changed to gcc 2.8.0 ! Having problems in liboctave :

...

This looks like a problem from gcc-2.7.2 - > gcc-2.8 ? 

  operator void* () const
    { return ok ()
        ? static_cast<void *> (-1) : static_cast<void *> (0); }

if I change the line to :
(void *) (-1) : (void *) (0); }
It compiles the file. But is it correct?? There more static_cast
problems in other files as well. :-(

I thought files compiled ok with gcc-2.7.2 should still compile with
the new version but it does not seem that way!
