Issue with eggMorphList.I source code

Just want to mention a problem while trying to build from CVS with Intel compiler

1>c:\...\panda\src\egg\eggMorphList.I(78): 
error: no operator "!=" matches these operands
1>operand types are: const epvector<EggMorphVertex> != const epvector<EggMorphVertex>
1>    return (_morphs != other._morphs);
1>                    ^


1>c:\...\panda\src\egg\eggMorphList.I(89): 
error: no operator "<" matches these operands
1>operand types are: const epvector<EggMorphVertex> < const epvector<EggMorphVertex>
1>    return (_morphs < other._morphs);

Any change to make in the source code? thanks!
