dlang/phobos pull request #8919 "Bump zlib to latest v1.3.1" was merged into
master:

- c97ea340c6706fc3dd416302ff4982ee6242fd4e by Martin Kinkelin:
  Bump zlib to latest v1.3.1

  Which should cleanly compile with C11 now, without walls of warnings
  with e.g. recent clang versions. Fixes Bugzilla Issue 24268.
