The above doesn't change the configure-time prefix, as far as
directories recorded in the binaries are concerned.  It just installs
under a different tree root.

It is convenient to do that when you are preparing a binary
distribution, because you then create a tree that includes a single
package.

The reason nt/INSTALL recommends this technique, as opposed to
DESTDIR, is because that is what I use.  And the reason I prefer not
to use DESTDIR is that it fails on Windows if --prefix specified a
Windows style absolute file name, as in --prefix=d:/usr, because you
cannot prepend any non-empty string to that without producing an
invalid file name.
