I'm at 1.875 and didn't notice any problem.  Perhaps a machine
dependency had crept into bison 1.75?  Prolly not worth trolling their
logfiles to find out.

If anyone else confirms the failure, though, we'll need to update our
own docs to specify bison >= 1.875 required.  I think it says 1.50
at the moment ...
