I see no reason to do that because the build will NOT fail.  In any
case, any such changes should be common to the Posix platforms, where
it would be really unusual to install within the source tree.

The whole point of this build method is to make the Windows port build
and install as it does on GNU/Linux.

No, you don't need "make install" to run Emacs that was built the old
way on Windows.  You do need to say "make" twice, because only the
second time picks up the updated DOC file.  This nuisance is gone in
the Posix build method.

I added that, thanks.
