Re: a probalem with Bison

[Paul Eggert]

Sorry, that test case didn't work for me; see below.  Apparently it
depends on a file algol.h that you didn't submit?

Can you please resubmit the test case, with algol.h included this
time?  Also, please test that untarring the test case into a fresh
directory and typing "make" illustrates the bug.  And please remind me
which versions of flex, bison, and GCC you're using.  Thanks.
