It syncs with gnulib version a8bac4d49. The main changes are:
- Remove the usage of anonymous union within DYNARRAY_STRUCT.
- Use DYNARRAY_FREE instead of DYNARRAY_NAME (free) so that
Gnulib does not change 'free' to 'rpl_free'.
- Use __nonnull instead of __attribute__ ((nonnull ())).
- Use __attribute_maybe_unused__ instead of
__attribute__ ((unused, nonnull (1))).
- Use of _Noreturn instead of _attribute__ ((noreturn)).
The only difference with gnulib is:

It seems a wrong sync from gnulib (the code is used on loader and
thus it requires __libc_fatal instead of abort).
Checked on x86_64-linux-gnu.
