My guess is that your build environment has updated bison recently.
Bison 3.3.0 and 3.3.1 were both released in the last week.

Yeah, this file is supposed to be created by bison.

You missed the first warning block, which is a little more interesting:

    configure: WARNING:
    
    I wasn't able to find a suitable style for declaring the api prefix
    in a bison input file so I'm disabling bison.  We expect bison to
    understand the '%define api.prefix { PREFIX }' syntax.

Octave's configure is attempting to do a feature test on bison, and it
failed. Unfortunately it looks like we don't have a good diagnostic for
why it failed. But it looks like configure is not happy with bison 3.3
right now. Can you take this to the bug tracker?

Thanks,
