Problem with top-of-trunk

[Efi Fogel]

Hi,

I've pulled the latest version.
I get the following warning (which I treat as an error):

position.hh:100:31: error: comparison between signed and unsigned integer
expressions [-Werror=sign-compare]

The relevant code of  position.hh follows:
     96     /// (column related) Advance to the COUNT next columns.
     97     void columns (int count = 1)
     98     {
     99       column =
    100         0 < count || -count < column
    101         ? column + count
    102         : 1;
    103     }
