warning: ISO C99 requires rest arguments to be used

With this #define: 

#define nerr_raise(e,f,a...) \
   nerr_raisef(__PRETTY_FUNCTION__,__FILE__,__LINE__,e,f,a)

this will generate a warning: 

nerr_raise (NERR_NOMEM, "No memory for new row");

whereas this won't: 

nerr_raise (NERR_NOT_FOUND, "Unable to find key %s", key);

To remove this warning, replace the previous #define with: 

#define nerr_raise(e,a...) \
   nerr_raisef(__PRETTY_FUNCTION__,__FILE__,__LINE__,e,a)
