the #if is the same as the upper one. Is this duplicated ?

Description
Tried building
rviz_ogre_vendorand MacOS 15 (Sequoia) with XCode 16.x and build fails as the newer versions of (apple)clangon macOS is does not provide default implementations ofstd::char_traitsfor non-standard character types like unsigned short and unsigned int.The PR adds a patch that provides explicit specializations for std::char_traits and std::char_traits. It defines all the necessary types and static member functions (like compare, length, copy, assign, etc.) that std::basic_string needs to operate on these character types.
Is this user-facing behavior change?
Yes
Did you use Generative AI?
Yes, patch file generated using Gemini Code Assist extension in VSCode.
