There is code in the Makefile that attempts to detect when the build and
source directories are not the same, and removes y.tab.[ch] from the build
directory when they are not. The problem is that when you run
`./configure', the source directory gets set to `.' and the build directory
gets set to the absolute pathname.  Those don't compare as equal, and the
files get removed.

I could solve that problem with a short `same_dir' script, but maybe
there's an easier way.
