New Revision: 339954
URL: https://svnweb.freebsd.org/changeset/base/339954

Log:
  Add __used to __CTOR_LIST__ and __DTOR_LIST__
  
  Enabling BSD_CRTBEGIN on amd64 resulted in
  error: unused variable '__CTOR_LIST__'.
  
  __CTOR_LIST__ is indeed unused in crtbegin.c; it marks the beginning of
  the .ctors array and is used in crtend.c.  Annotate __DTOR_LIST__ as
  well for consistency.
