New Revision: 256055
URL: http://svnweb.freebsd.org/changeset/base/256055

Log:
  Disable use of compiler atomic builtins. For APR, this is limited to
  architectures where they are known not to work. For SVN itself, use
  the least common denominator and disable them across the board. This
  allows svnlite to build and run on all FreeBSD architectures.
