Ok, I haven't looked at the contents, but agree that keeping them around
is useful. The only bits which might break anything are the build changes.

Have you confirmed that this genuinely does nothing during a normal
build? I note you've included tools as a SUBDIR in hivex/Makefile.am
which, as I understand it, will cause make to be executed with the same
target as the parent directory on every invocation. Does 'make' without
arguments genuinely do nothing in that directory? I vaguely recall that
it will default to building the first target, which would be
visualizer.opt here.

It might be better not to specify tools as a SUBDIR in hivex/Makefile.am.
