older setfs sintax to newer g++ 3.0.2

[Giuseppe Zompatori <joesunny at tiscalinet dot it>]

Hi there,

I'd greatly appreciate any help with changing the following old code(ca. 1997)
to the new ISO standards.

<snip>
ostream &operator<<(ostream &io,const Cone &d)
{
 io.setf(ios::showpoint+ios::right+ios::fixed);
 io << "Cone " << d.height << " " << d.radius << " " << d.thetamin << "-" << 
d.thetamax << " " << d.zmin << "-" << d.zmax << "\n";
  return io;
} 
</snip>

gcc 3.0.2 fails with the following error:

g++-3.0.2 -c -W -ansi -O3 -mcpu=i586 -march=i586 -fomit-frame-pointer
-ffast-math -malign-double -fpack-struct -fno-exceptions -fno-rtti cone.cpp -o

   std::ios_base::setf(std::_Ios_Fmtflags, std::_Ios_Fmtflags)
make: *** [cone.o] Error 1
What's the new sintax for setf?
I am not able to determinate it by myself as I am not even an hacker.
Again any help greatly appreciated.

Thanks in advance,

Giuseppe
