This code (from OpenBSD ftp client):

void
restart(argc, argv)
        int argc;
        char *argv[];
{
        quad_t nrestart_point;
        char *ep;

        if (argc !=3D 2)
                fputs("restart: offset not specified.\n", ttyout);
        else {
                nrestart_point =3D strtoq(argv[1], &ep, 10);
                if (nrestart_point =3D=3D QUAD_MAX || *ep !=3D '\0')
                        fputs("restart: invalid offset.\n", ttyout);
                else {
                        fprintf(ttyout, "Restarting at %qd. Execute get,
put or"
                                "append  to initiate transfer\n",
/* line 2169 */                 nrestart_point);
                        restart_point =3D nrestart_point;
                }
        }
}

gives this warning, compiling on FreeBSD 4.0-20000101-CURRENT alpha:

gcc -c -g -O2 -Wall -Wno-unused -I/house/luna/bsd_a/include -I./libedit
-DHAVE_CONFIG_H -I.  -o cmds.o cmds.c
cmds.c: In function `restart':
cmds.c:2169: warning: long long int format, quad_t arg (arg 3)

Why? The format is "%qd" and the variable nrestart_point is a quad_t.
Shouldn't be any problems, right? It compiles clean on OpenBSD and Linux
(both i386 though).
