Description James Cloos 2013-04-19 18:23:17 UTC 
The 64 bit arguments in question are of time_t, __time_t and __off_t:

qcheck.c:166:7: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 5 has type ‘__time_t’ [-Wformat=]
       fprintf(fpx, "obj %s %s %lu\n", e->name, hashed_file, st.st_mtime);
qcheck.c:193:7: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 5 has type ‘__time_t’ [-Wformat=]
       fprintf(fpx, "obj %s %s %lu\n", e->name, e->digest, st.st_mtime);

         printf("%s%lu%s seconds", GREEN, (t[1] - t[0]), NORM);

   warnf("File is too big: %lu", st->st_size);


I’m not sure whether reports like this are wanted for bug #393673 (the x32 porting issues tracker) given that, since the arch is little endian, the results will be accurate as long as they are <4G.  Please note whether little things like this should be reported blocking #393673.
