These items were used for statistics tracking, but no code at all exists to consume them. By removing them we save a) space because they counters required space, and did so in each and every json object b) performance because calloc() needs to write less data and the counters are no longer maintained; cache performance can be better, load on OS main memory is lighter We could conditionally enable/disable these counters, but I have not done this they were really nowhere used and it looked more like a left-over from the import of hashtable code.

Building on Unix with git, gcc and autotools
Home page for json-c: https://github.com/json-c/json-c/wiki
Caution: do NOT use sources from svn.metaparadigm.com, they are old.
Prerequisites:
gcc,clang, or another C compilerlibtool
If you're not using a release tarball, you'll also need:
autoconf(autoreconf)automake
Make sure you have a complete libtool install, including libtoolize.
json-c GitHub repo: https://github.com/json-c/json-c
$ git clone https://github.com/json-c/json-c.git
$ cd json-c
$ sh autogen.sh
followed by
$ ./configure
$ make
$ make install
To build and run the test programs:
$ make check
Linking to libjson-c
If your system has pkgconfig,
then you can just add this to your makefile:
CFLAGS += $(shell pkg-config --cflags json-c)
LDFLAGS += $(shell pkg-config --libs json-c)
Without pkgconfig, you would do something like this:
JSON_C_DIR=/path/to/json_c/install
CFLAGS += -I$(JSON_C_DIR)/include/json-c
LDFLAGS+= -L$(JSON_C_DIR)/lib -ljson-c
