commit 8b41fb08f00f01fe0dd8b2b5455d3422d97ddc60
Author: Werner Koch <wk at gnupg.org>

    core: Silence newer compiler warnings.
    
    * configure.ac: Add -Wno-format-truncation and
      -Wno-sizeof-pointer-div.
    * src/b64dec.c (_gpgme_b64dec_proc): Add fallthrough annotation.
    * src/cJSON.c (parse_string): Ditto.
    * src/gpgme-json.c (main): Ditto.

    gcc 8 enables a couple of new warnings.  Some of them are useless for
    us.  In particular:
    
      util.h:42:26: warning: division 'sizeof (char *) / sizeof (char)'
      does not compute the number of array elements [-Wsizeof-pointer-div]
      #define DIM(v) (sizeof(v)/sizeof((v)[0])) ^
    
      trustlist.c:101:22: note:
      in expansion of macro 'DIM' if (strlen (p) == DIM(item->keyid) - 1)
    
    Which is a real standard way to use DIM, here the right hand side is
    equivalent to sizeof but nevertheless it is correct.  Yes sir, we know
    C.
    
    The format string warnings I have seen were assuming that the time
    structure returns valued out of scope - but if the system is that
    broken, the s_n_printf catches this.
