failure to build against json-c master

[Jeff McKenna]

• issue seems similar to ticket#5449

• using json-c master and gdal-trunk

• platform: Ubuntu 14.04.1 LTS

• error during compile of GDAL:

trunk r28021 "ARG: remove test against error_ptr(-1) that is historical value, no longer returned by libjson-c >= 0.11 (#5755)"

I didn't actually try compiling against json-c master, so other errors could potentially popup. Reopen if needed.

verified with json-c master. Thanks!!!
