Nah.  That's really for the O/S distributions to do (or anyone who's
attempting to create a "package").  I'm merely suggesting two things:

1. If a program can do a "make install", it should have a "make
   uninstall" to go with it.  
2. To allow for source removal, "make install" should install an
   uninstaller (like this: "make -n uninstall > uninstaller; install
   uninstaller").

I've worked on UNIX distributions that don't use things like RPM, DEB,
and so on.  That was okay as all I wanted to do was download the
program, configure it, install it, and remove the excess (source).  At
some point in the future, I (or my successor) might want to remove the
installed program.  That's where having an uninstaller in #2 to
unambiguously list what needs removing comes in.

This is probably more of a GNU tools (autoconf/automake) issue, but
GNU Emacs has in the past used a highly hacked configure tool (does it
still?), so it might apply here as well.

Exactly.  My contention is that /tmp/foo should be installed right
along with everything else.

        Must be an Exceed thingy.
        I'm using Windows and running Emacs directly; no X of any kind.
        The Alt goes to menus in OTHER windows, but the Emacs window
        doesn't grab the Alt; it works as Emacs intended.  This is only
        true if the Emacs window (/frame) is SELECTED.
        Exceed is probably the culprit, not letting your Alt get to
        the Emacs app.

You can ask Exceed to send other keycodes.
Configuration -> Keyboard Input
There you can graphically edit your keyboard mapping.  But see below.

Configuration -> Keyboard Input
Under 'Window Modifier Behaviour', you can set
Alt Key:    To X / To Windows / Left to Windows Right to X ...
Window Key: To X etc.

Note that this will only affect the programs running under Exceed. I
think this is the preferred solution.

Given a propertied string, how can I clear _all_ its properties?
There's a buffer-substring-no-properties, but I can't find anything
like substring-no-properties.  remove-text-properties requires that I
know the set of possible properties in advance, which I don't (or
rather, the set is infinite in my case).
