    libcxx-compat: fix llvmorg-21-init-18351-gfcc09b6f0267:
    
      [libc++] Fix std::make_exception_ptr interaction with ObjC (#135386)
    
      Clang treats throwing/catching ObjC types differently from C++ types,
      and omitting the `throw` in `std::make_exception_ptr` breaks ObjC
      invariants about how types are thrown/caught.
    
      Fixes #135089

    Only use lambdas when in !defined(_LIBCPP_CXX03_LANG), so this will
    compile with clang 18 and lower, in C++03 mode and earlier.
