New Revision: 229087
URL: http://svn.freebsd.org/changeset/base/229087

Log:
  MFC r228546:
  
    Clang has more warnings enabled by default, and when using -Wall, so if WARNS
    is set to low values, some of them have to be disabled explicitly.
  
  MFC r228551:
  
    Disable one more clang warning when WARNS <= 3.
  
  MFC r228606:
  
    Add a NO_WARRAY_BOUNDS setting to bsd.sys.mk, only applicable to clang,
    to selectively work around warnings in programs that don't use flexible
    array members, but instead define arrays of length 1 at the end of the
    struct, and then access those beyond their declared bounds.
  
  MFC r228617:
  
    Disable yet another clang warning when WARNS <= 3.
  
  MFC r228675:
  
    Disable yet another clang warning (-Wconversion) when WARNS <= 3.
  
  MFC r228677:
  
    Disable another clang warning (-Wempty-body) when WARNS <= 2.
