Description Alfred Wang CLA 2011-07-18 03:54:46 EDT 
CDT reports them as problem declarations. The definitions of these two structs locate /usr/include/c++/4.2.1/bits/cpp_type_traints.h. Here is a sample test case.

template<typename _Tp>
struct __is_pod
{
};

template<typename _Tp>
struct __is_empty
{
};

If I remove the first underline, CDT8 will be OK. It's like here.

template<typename _Tp>
struct _is_pod
{
};

template<typename _Tp>
struct _is_empty
{
};

I am aware that GCC 4.4 has removed these two structs.
Comment 1 Markus Schorn CLA 2011-07-27 09:01:42 EDT 
I made the support for the builtin type-traits dependent on the version of gcc. I cannot do the fix on the maintenance branch, to work around the issue you can map __is_pod to something different in the project settings 'C/C++ - General - Paths and Symbols - Symbols - C++'.
