- Global _LH_INLINE  
- Don't use this outside of linkhash.h:  
- Global _LH_UNCONST  (a)
- Don't use this outside of linkhash.h:  
- File bits.h  
- Use json_util.h instead. 
- Global error_description  (error)
- Global error_ptr  (error)
- Global hexdigit  (x)
- Global is_error  (ptr)
- Global json_tokener  
- Unused in json-c code  
- Global lh_abort  (const char *msg,...)
- Since it is not a good idea to exit the entire program because of an internal library failure, json-c will no longer use this function internally. However, because its interface is public, it will remain part of the API on the off chance of legacy software using it externally.  
- Global lh_table_lookup  (struct lh_table *t, const void *k)
- Use lh_table_lookup_ex() instead.
