Subject: [PATCH] committed patch 1710682 by jfaith - in src/libcola/cola.cpp,
 isnan is used and not the cross-platform definition isNaN defined in isnan.h
 => replaced isnan by isNaN and included isnan.h - add math.h include in
 src/libcola/gradient_projection.cpp This was necessary because libcola does
 not compile for OS X 10.3.9
