    11No I think it's correct. Setting _XOPEN_SOURCE to 500 is equivalent to setting _POSIX_C_SOURCE to 199506, and strdup was only added to POSIX in POSIX.1-2001. Before that, strdup was an X/Open extension, and you had to define _XOPEN_SOURCE_EXTENDED to use it on systems that implemented those extensions. Understandably, Apple only implements the POSIX requirements and _XOPEN_SOURCE_EXTENDED does nothing on current macOS.
