_GNU_SOURCE defines the kitchen sink, and also prefers glibc definitions where glibc and POSIX conflict. Even though POSIX is worth less than toilet paper, we still prefer the POSIX definitions. rar.c needs asprintf(), which is _GNU_SOURCE-only. So we define _GNU_SOURCE too specifically for this file.
