Description:
 def contains_parent_dir(fpath, dirs):
 """ Returns true if paths in dirs start with fpath. Precondition: dirs and fpath should be normalized before calling this function. """

    # Note: this function is used nowhere in pygccxml but is used
    # at least by pypluplus; so it should stay here.

    return bool([x for x in dirs if _f(fpath, x)])
