File statistics (using stat() and

Note: The stat() and lstat() functions are sufficient for
non-Windows systems.
On Windows systems the st_dev and st_ino components may contain
dummy contents, the stat structure does not contain information
about symbolic links.
For a portable (both Windows and non-Windows) check whether a file
is a symbolic link, reparse point... use the dk4_file_info_t
data type from dk4fileit.h and the functions from dk4filei.h.
