To Artifact [6f2726fb11]:

• File src/macros.h — part of check-in [b7097a67b6] at 2015-06-14 10:45:10 on branch trunk — Add OF_NONNULL / OF_NULLABLE and use that instead

  Using __nonnull directly doesn't work on systems using glibc, as glibc
  defines __nonnull as a parameterized define. While this does not fix the
  problem of Clang introducing __nonnull even though it conflicts with
  glibc, this at least means it's possible again to compile things with
  versions of Clang that don't support __nonnull on systems with glibc. (user: js, size: 14648) [annotate] [blame] [check-ins using]
