  r276527:

  Don't install h_raw if dealing with clang 3.5.0+ to unbreak the tests2
Jenkins
  job

  The h_raw application doesn't do proper bounds checking without the option
  being supplied via the build, which means that it doesn't throw signals and
  fail as expected

  r277648 (by jilles):

  Enable utimensat tests from NetBSD.

  As with other tests from c063, a required #include <sys/stat.h> was missing.

  r279154 (by jilles):

  nice(): Correct return value and [EPERM] error.

  PR:           189821
  Obtained from:        NetBSD
  Relnotes:     yes

  r279397 (by jilles):

  nice(): Put back old return value, keeping [EPERM] error.

  Commit r279154 changed the API and ABI significantly, and {NZERO} is still
  wrong.

  Also, preserve errno on success instead of setting it to 0.

  r283584 (by emaste):

  memmem(3): empty little string matches the beginning of the big string

  This function originated in glibc, and this matches their behaviour
  (and NetBSD, OpenBSD, and musl).

  An empty big string (arg "l") is handled by the existing
  l_len < s_len test.
