[graph] king ordering: get rid of "comparison between signed and unsigned" warning

8 Sep 2005

This patch allows to get rid of the
"comparison between signed and unsigned" warning,
issued by gcc 3.4.4 at -Wall.
I'm not sure of the correctness
of the (int)Qptr->size() cast.

Regards,

Marco Morandini
