# This test checks that the following works properly:
# - A C file is used as a source, it needs to be scanned for included files.
# - One of the included files is a target in a dependency.
# - If the dependency changes the included file to include other files than
#   before the list of dependencies must be redone.
# - The source file is in a subdirectory, it should find included headers
#   there.
