+// - Stripped GCC attributes()
+// - Removed extern "C" from the cxa_demangle function
+// - Added "#undef _LIBCPP_EXTERN_TEMPLATE" to avoid warning
+// - Implemented missing rebind, construct, destroy in malloc_alloc
+// - Replaced noexcept, constexpr, alignas with their LLVM_* equivalents
+// - Included win32.h for snprintf implementation for MSVC
+// - Removed constexpr member initialization for MSVC
+// - Changed argument to alignas() to a literal for MSVC
