Right. But I suppose it isn't completely obvious to every user why deleting
a file with a few mouse clicks generates a different behaviour from using a
command line. :-)

It is already built-in. You can specify a list of TMP_DIRS under which files
are really unlinked. A few other options are also available.

I don't know. The lib itself only uses ISO C together with a few Unix
specific system calls (the only GNU libc specific function used is
get_current_dir_name() rather than getcwd(), which might easily be changed).
