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

From: Marco Morandini (morandini_at_[hidden])

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
