[PATCH v3 1/9] json: Remove invalid typedef redefinition |
Date: |

The C standard does not allow for typedef redefinitions, even if they
map to the same underlying type. In order to avoid including the
"jsmn.h" in "json.h" and thus exposing jsmn's internals, we have exactly
such a forward-declaring typedef in "json.h". If enforcing the GNU99 C
standard, clang may generate a warning about this non-standard
construct.
Fix the issue by using a simple `struct jsmntok` forward declaration
instead of using a typedef.
