Hi,

Thanks for your report.

I've tried the same input sequence with info, and it doesn't work,
either, with an error message "Cannot find node `Top'." So info and the
info reader inside emacs have the same behavior here.

The reason why I've switched to direntry stub instead of symlinks for
/usr/share/info/gcc.info.gz:

                   $ info gcc 
With symlinks       
                   shows "10 'gcov'--a Test Coverage Program" in
                   gcc-4.8.info, while gcc-4.9 is the symlinked
                   default version.
With direntry stub
                   shows the top node in gcc-4.9.info.

The drawback is that with direntry stubs, there's no "(gcc)" top nodes,
only "(gcc-4.9)" top nodes, etc. However, it doesn't seem to be a good
idea to revert to symlinks. Any patches are welcome.

Regards,
Yixuan
