All the branches are run through clang (ccc-analyzer).  Ignoring the
errors from ATF we have the following warnings which have been evaluated
and marked to be ignored:

HEAD:
IGNORED: rpz.c:193:3: warning: Value stored to 'str' is never read
IGNORED: getaddrinfo.c:430:31: warning: The right operand to '+' is always 0
IGNORED: ./main.c:368:21: warning: Both operands to '!=' always have the same value

9.6:
IGNORED: getaddrinfo.c:430:31: warning: The right operand to '+' is always 0
IGNORED: ./main.c:314:21: warning: Both operands to '!=' always have the same value

9.7:
IGNORED: getaddrinfo.c:430:31: warning: The right operand to '+' is always 0
