So right you are.  :)  I've just checked this fix into the tree:
http://mail.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20030818/006326.html

This means that everyone should do something like this next time you want
to update your tree:

cd ~/llvm            # from the top...
make cleandeps       # remove all .d files
utils/cvsupdate.sh   # Get new Makefile.common
make                 # rebuild all "new and improved" .d files

The new .d files won't cause errors when headers get moved, so I removed
the 'cleandeps' target from CVS, it should be unnecessary now.  :) :)

If you update your tree before running cleandeps, you can manually remove
all .d files as before with a 'find' command.

Thanks Casey!
