Indeed, we should include all three, and according to [compliance],
there's a couple more headers that we should provide (cwchar, cstring,
cerrno, and cmath, but these are probably significantly more involved,
so we can handle them separately).

As guessed, the omission was not intentional.

If you could, add those two to the patch as well, edit Makefile.am and
regenerate using automake 1.15.1, and see
https://gcc.gnu.org/contribute.html wrt. changelogs in commit messages.

Thank you!  Have a lovely day :-)

The headers mentioned in this PR are provided in freestanding,
partially, in 13 already, indeed.
