I checked into this one, patches were submitted for the trunk and
installed back in June for these problems.  E.g. see:
http://gcc.gnu.org/ml/gcc-patches/2002-06/msg01614.html

I guess this and other similar patches for the other .y files weren't
backported to the 3.2 branch.  This shouldn't be too bad since the
actual GCC-3.2.x release tar file will contain the necessary bison
output of a suitable bison version.  In the mean time, I suggest just
not using bison-1.50 for testing 3.2.x CVS snapshots.

I'll leave it to our release manager to decide if this issue warrants
backporting the relevant patches or not.

	Thanks for reporting this,
