--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
Based on the test output it looks like the failures are caused by the same
underlying problem as bug 78959 (HP-UX printf lacking full support for the hh
and h length modifiers), and by bug 78133 (lack of support for %a).  As noted
in the former bug it should be possible to resolve both by adding "
dg-require-effective-target c99_runtime" to the tests, although it would be
better to break out the failing tests into their own file so that the others
that do not require full C99 support can still be exercised even on C89
implementations.

The failure in test_f_long_double:530 look new.
