recent lalr1.cc patches break test cases 90-93 on my host.

[Paul Eggert]

Also, I am now getting more test failures from CVS Bison, which I
expect are a result of the recent changes to data/lalr1.cc.  Here they
are.  My platform isDebian GNU/Linux 3.0r1 x86, gcc 3.4.3.  Can you
please look into this too, while you're at it?  (I know you have so
much free time.  :-) Thanks.
