Bug#656659: info not showing anything with certain build flags

[karl@freefriends.org (Karl Berry)]

    Does anyone have an idea why this might happen?

Not out of my head.  And Sergey's main server (gnu.org.ua) apparently
developed hardware woes, so I doubt he'll be able to answer anything
Texinfo-related quickly.

    (I tried compiling current sources, but that didn't work out, 

Sergey has made a ton of changes since info 4.13.  Really need to work
from the development sources.  I can try compiling with your options at
some point.

(BTW, it is explicitly not a goal for Texinfo, or GNU packages in
general, to compile with -Wall, although some individual maintainers
choose to do so.  I doubt that's relevant to the problem at hand,
anyway.)
