# 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 (!)
