Author: dim Date: Sat Dec 31 13:37:25 2011 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.
