I pushed the fix to the branch. Can we remerge it?

I think best way would be to create another MR.

You should also add
  #include <petscsection.h>
to petscdmlabel.h.
This which will also satisfy Lisandro's point.

Also, I do not understand why tests did not catch this. Its obvious what happened. I added that header
to convert.c instead of convest.c.

How come this was not caught by the tests? I think we have tests with -Werror

The warnings below are from a C build. A C++ build fails right away.

We need to `#include <petscsection.h>` somewhere in the public headers, at least such that  `#include <petsc.h>` in user code works.

$ git grep petscsection include/
include/petsc/private/sectionimpl.h:#include <petscsection.h>
include/petscis.h:#include <petscsectiontypes.h>
include/petscsection.h:#include <petscsectiontypes.h>
