I initially ran into it when compiling code that used ITK with
-std=gnu++0x set in CXX_FLAGS. I just tried what you suggested -
attempting to build ITK with the same flag, but I get the same

/home/doriad/src/ITK/Modules/ThirdParty/VNL/src/vxl/core/vnl/vnl_math.h:87:53:
error: ‘constexpr’ needed for in-class initialization of static data
member ‘e’ of non-integral type

Has any one else tried to build ITK with this flag?
