    _______________________________________________________

Details:

I recently upgraded from bison 3.2.4 to bison 3.3.1 and the Octave build from
Hg (both stable and default) started failing.

Warnings in configure output indicate it's not recognizing the new bison:


checking for bison... bison -y
checking syntax of bison api.prefix (or name-prefix) declaration... 
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.

configure: WARNING: 

I didn't find bison, or the version of bison that I found does not
support all the features that are required, but it's only a problem
if you need to reconstruct parse.cc, which is the case if you're
building from VCS sources.

Downgrading to bison 3.2.4 fixed the build.
