 # Reasons for requiring this library version:
 #
 # 1) RFC 4627, the JSON "memo" (it is *NOT* a standard!) helpfully fails
 #    to specify the maximum size of an integer type. And yet, JSON is
 #    supposedly a subset of ECMA-262, which specifies a Number type to
 #    be 64-bits.
 #
 #    The loose JSON "memo" might expalain why older versions of JSON-C encode
 #    a JSON Number in sizoef(int) bytes which is only 32-bits on 32-bit
 #    systems. This is not acceptable for Upstart which needs to be able
 #    to encode 'size_t' and 'unsigned long' types which can be larger
 #    than 'int'.
 #
 # 2) New json_tokener_parse_verbose() function required to detect invalid
 #    JSON (!)
