Yeah, probably.  Or someone could redo the Makefile in Automake, which
automates all this.

I can't emphasize enough how much nicer it is to assume GNU make than
to try to be portable.

Andrew> Auto dependency tracking would be very nice to have though. :)

I've appended a patch to do it.  I made this against the python
repository on gitorious -- but aside from the extra code for the
python objects, it would be the same for the trunk.  The patch is
nearly all deletions.

Give it a whirl & let me know what you think.  No ChangeLog entry yet,
sorry.
