New Revision: 316779
URL: https://svnweb.freebsd.org/changeset/base/316779

Log:
  Temporarily revert r315602.
  Bring back the definition for the GCC __nonnull() attribute.
  
  Old versions of GCC, including the version installed the latest 11-stable
  snapshot with pkg(8), still carry the old attributes.
  
  The issue is easily fixed by rebuilding GCC but there is no need to cause
  havoc in our user base. The definition by itself is harmless but it should
  be removed again in the near future.
