Hello Martin,
Thanks for the test. I committed it with minor tweaks:
- Add comments to the shell script.
- In the .c file, include <unistd.h>. By convention, in gnulib, we
include the specification header file right after config.h. In some
situations, this allows to uncover bugs.
- In the .c file, include <stdlib.h>, needed for abort().
