Hello,

Below is a list of files, that contain:
#if defined(__GNUC__)
#pragma GCC system_header
#endif
which causes a warning on my TI compiler.

E:\boost\include\boost-1_50_0\boost\exception\all.hpp
E:\boost\include\boost-1_50_0\boost\exception\current_exception_cast.hpp
E:\boost\include\boost-1_50_0\boost\exception\detail\error_info_impl.hpp
E:\boost\include\boost-1_50_0\boost\exception\detail\exception_ptr.hpp
E:\boost\include\boost-1_50_0\boost\exception\detail\is_output_streamable.hpp
E:\boost\include\boost-1_50_0\boost\exception\detail\object_hex_dump.hpp
E:\boost\include\boost-1_50_0\boost\exception\detail\type_info.hpp
E:\boost\include\boost-1_50_0\boost\exception\diagnostic_information.hpp
E:\boost\include\boost-1_50_0\boost\exception\errinfo_errno.hpp
E:\boost\include\boost-1_50_0\boost\exception\exception.hpp
E:\boost\include\boost-1_50_0\boost\exception\get_error_info.hpp
E:\boost\include\boost-1_50_0\boost\exception\info.hpp
E:\boost\include\boost-1_50_0\boost\exception\info_tuple.hpp
E:\boost\include\boost-1_50_0\boost\exception\to_string.hpp
E:\boost\include\boost-1_50_0\boost\exception\to_string_stub.hpp
E:\boost\include\boost-1_50_0\boost\throw_exception.hpp
E:\boost\include\boost-1_50_0\boost\type_traits\is_virtual_base_of.hpp

In other files, i.e. boost\integer.hpp, I've found this #pragma guarded
against __GNUC__ >= 4:
#if defined(__GNUC__) && (__GNUC__ >= 4)
#pragma GCC system_header
#endif
which doesn't cause a warning on my compiler, because it defines __GNUC__
to 3.

Could this be fixed in the files on the list above, or are there some
__GNUC__ 3 compilers, that need this pragma to be enabled?

Regards,
Kris
