I was hoping that we could go straight to Bison 2.1, as the patches
since 2.0b are so minor.

Thanks for reporting the problem.  I guess the wget guys have
changed the syntax for disabling caches.  I unbended a bit on
my usual insistence that everyone upgrade to the latest stable
version and installed the patch enclosed below.

> ++ in README-cvs version numbers for tools are missing

I'd rather not put version numbers in there, as we'd have to maintain
the numbers.  Let's just continue to say 'latest stable version'.
I agree we should mention Valgrind and Wget, though.

I installed this; I hope it fixes your wget problem.

        * bootstrap (no_cache): New var, to accommodate different wget
        variants.  Use it instead of '-C off'.  Problem reported by
        address@hidden

        * README-cvs: Give URLs for recommended tools.
        Mention Gzip version problem, and bootstrapping issues.
        Remove troubleshooting section, as it's somewhat obsolete.
