# 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 (!)
