Commit ID	4b7dbb3922a0c563d74be4474b0cbdc1b00b4595
Author	Marco Costalba

Fix KpsK endgame Broken by commit a44c5cf4f77b05a03 of 3 /12 / 2011 that was labeled "No functional change" because our 'bench' test didn't triggered that particular endgame. Indeed we need to run a specific bench on a set of endgames position when touching endgame.cpp because normal bench does not cover endgames properly. Found by MSVC 2012 code analyzer.
