Typo in ChangeLog entry: s/stdbool/stdint/. Other than that, the patch
looks fine. Thanks!

  $ ./gnulib-tool --test --without-tests

is a way to check whether the dependencies are complete, at least
regarding the platform on which you are running this.

When 'xalloc-oversized' is present through indirect dependencies, we
don't have an automated way to find that it's missing as a direct
dependency in the module description.

For POSIX function modules, we do have a mechanism:
