Scratch that, I believe three notes didn't get sent out.  This is the third.

Looking at bison log, the only significant change between 1.25 and 1.27
is a re-numbering of tokens, so that they now start at 257 as advertized.

So there are two basic possibilities: either objc-parse was the only parser
that was rebuilt, in which case it's quite normal it broke (since C/objc
parsing are VERY tightly linked), or egcs somehow came out to rely on that
bison bug...

I don't have any machine in a decent state to check either conjecture 
right away... Jeff, which version of bison is used these days ?
