Visual Studio 2013: C++: Intellisense Error for Enum '|' -

i have enum below:

enum myfilter {     myfilter_none = 0,      myfilter_line = 1,      myfilter_arcccw = 2,      myfilter_arccw = 4,      myfilter_circle = 8,      myfilter_arc = myfilter_arcccw | myfilter_arccw,      myfilter_all = myfilter_line | myfilter_arc | myfilter_circle }; 

this compiles fine in vs 2010. when ported same vs 2013, error.

intellisense: expression must have constant value 

the error thrown | in myfilter_arc , myfilter_all.
though linking successful, intellisense error, resolve this. doing wrong?
