* printbuf.c - C. Watford (christopher dot watford at gmail dot com)
Added a Win32/Win64 compliant implementation of vasprintf
* debug.c - C. Watford (christopher dot watford at gmail dot com)
Removed usage of vsyslog on Win32/Win64 systems, needs to be handled
by a configure script
* json_object.c - C. Watford (christopher dot watford at gmail dot com)
Added scope operator to wrap usage of json_object_object_foreach, this
needs to be rethought to be more ANSI C friendly
* json_object.h - C. Watford (christopher dot watford at gmail dot com)
Added Microsoft C friendly version of json_object_object_foreach
* json_tokener.c - C. Watford (christopher dot watford at gmail dot com)
Added a Win32/Win64 compliant implementation of strndup
* json_util.c - C. Watford (christopher dot watford at gmail dot com)
Added cast and mask to suffice size_t v. unsigned int conversion
correctness
* json_tokener.c - sign reversal issue on error info for nested object parse
spotted by Johan Bj�rklund (johbjo09 at kth.se)
* json_object.c - escape " in json_escape_str
* Change to automake and libtool to build shared and static library
