 166 # DESCRIPTION
 167 #
 168 #   Checks for a fully C99 compliant snprintf, in particular checks whether
 169 #   it does bounds checking and returns the correct string length; does the
 170 #   same check for vsnprintf. If no working snprintf or vsnprintf is found,
 171 #   it prints an error message and aborts.
