SANITIZE: a total of 2 files that should probably not be in your source tree
  has been found. A script shell file
  "/home/elfring/Projekte/Coccinelle/1.0.0-rc23/_build/sanitize.sh" is being
  created. Check this script and run it to remove unwanted files or use other
  options (such as defining hygiene exceptions or using the -no-hygiene
  option).


Would you like to improve this situation?
