 // test get_new_handler
 
-// FIXME: When libc++ is linked against vcruntime (i.e. the default config in
-// MSVC mode), the declarations of std::set_new_handler and std::get_new_handler
-// are provided by vcruntime/UCRT's new.h. However, that header actually only
-// declares set_new_handler - it's missing a declaration of get_new_handler.
