GNU Global cannot find definitions in standard libraries

[Tu Do]

Part of std::map template class:

template <typename _Key, typename _Tp, typename _Compare = std::less<_Key>,
            typename _Alloc = std::allocator<std::pair<const _Key, _Tp> > >
    class map
    {
    public:
      typedef _Key                                          key_type;
      typedef _Tp                                           mapped_type;
      typedef std::pair<const _Key, _Tp>                    value_type;
      typedef _Compare                                      key_compare;
      typedef _Alloc                                        allocator_type;
.....
     }

• What is your environment (OS)? 
• Ubuntu 13.10

• Which version of GLOBAL are you using? 
• 6.2.12

• What did you do? (command line) 
• Create gtags files from /usr/include, which includes standard header files from C++ and search for its definitions, by the following steps:
• mkdir ~/.gtags
• cd ~/.gtags
• ln -s /usr/include include
• gtags
  
• global -d map (or set, or list....)
  

• What did you expect from it?
  
• Displayed correct path to stl_map.h because std::map is located in /usr/include/c++/4.8/bits/stl_map.h
  

• What was occurred? (as is)
• A list of results from other header files, but no result for  "/usr/include/c++/4.8/bits/stl_map.h", which is the path to stl_map.h. Seems like gtags having problem parsing template objects? The current list of results:

include/boost/container/map.hpp
include/boost/fusion/container/map/detail/map_forward_ctor.hpp
include/boost/graph/distributed/adjacency_list.hpp
include/boost/icl/map.hpp
include/boost/locale/boundary/index.hpp
include/boost/mpi/python/serialize.hpp
include/boost/msm/back/dispatch_table.hpp
include/boost/msm/back/metafunctions.hpp
include/boost/polygon/detail/polygon_45_touch.hpp
include/boost/unordered/detail/unique.hpp
include/c++/4.7.3/ext/throw_allocator.h
include/c++/4.7/ext/throw_allocator.h
include/c++/4.8.2/ext/throw_allocator.h
include/c++/4.8/ext/throw_allocator.h
include/llvm-3.4/llvm/Analysis/PathProfileInfo.h
include/llvm-3.4/llvm/Bitcode/Archive.h
include/llvm-3.4/llvm/CodeGen/LiveStackAnalysis.h
include/llvm-3.4/llvm/MC/MCContext.h
include/llvm-3.4/llvm/MC/MCDwarf.h
include/qt4/Qt/qmatrix4x4.h
include/qt4/QtGui/qmatrix4x4.h

It can find map from boost but not from STL.
