-----------------------------------------------------------------

Update: compiling with {{-m32}} - at least with a sample program - causes the warnings to appear:

{noformat}
cc -m32    time.c   -o time
time.c: In function ‘main’:
time.c:11:17: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 3 has type ‘time_t’ {aka ‘long long int’} [-Wformat=]
   11 |   printf("%zu %lu\n", sizeof(time_t), now);
      |               ~~^                     ~~~
      |                 |                     |
      |                 long unsigned int     time_t {aka long long int}
      |               %llu

> musl 1.2 switched time_t to 64bit [0].
> glibc still defaults to 32bit, but starting with v2.34 has a macro to
> swich to 64bit too.
> Use the PRId64 format specifier for time_t to work with both settings,
> fixing [2].
