        Right - I think if it is not set; you can specify the value in the
macro thus:

AC_ARG_ENABLE(mozilla,
[  --disable-mozilla       OO.o usually includes a strangely hacked up mozilla
                          binary for your platform, to build without this
                          version, use this option.
],,enable_mozilla="yes")

        in this case you'd want enable_foo="auto" or something, and then detect
and work out what auto should be for that system.

        Correct - that's what we want ;-)

        Quite ! :-) that is important for packagers to stay sane.
