Description:
GCC 6.1 has just been released. Compiling trunk with it gives new sets of warning such as:

sql/item_timefunc.cc: In member function ‘void Item_func_str_to_date::fix_from_format(const char*, size_t)’:
./repo/mysql-joh/sql/item_timefunc.cc:3298:21: error: logical ‘and’ of equal expressions [-Werror=logical-op]
   for (; val != end && val != end; val++)
          ~~~~~~~~~~~^~~~~~~~~~~~~

libbinlogevents/src/uuid.cpp:72:5: error: this ‘if’ clause does not guard... [-Werror=misleading-indentation]
     if (*in_string != '{' || in_string[TEXT_LENGTH + 1] != '}')
     ^~

storage/innobase/include/ut0dbg.h:46:20: error: nonnull argument ‘col’ compared to NULL [-Werror=nonnull-compare]
  if (UNIV_UNLIKELY(!(ulint) (EXPR))) {   \
                    ^~~~~~~~~~~~~~~
