This is quite easy, the file is added explicitly in get_MANIFEST.

Done. Can you check what I did in config/Makefile.SH (look for 'funclist') ?

I am not sure how to do this. As long as the generated files end up in
the source tree (even if created elsewhere), two threads may try to 'mv'
identical files to the same spot at the same time.

I don't think what I've done prevents this.
