This change is a correct one to make, but I've slightly lost track of the kdelibs release policy.

This patch isn't fixing an issue anyone is actually hitting, right? And it's not like qglobal.h in Qt 4 is going to have any significant changes made to it. So it's possible this doesn't pass the threshold of bug fixes for kdelibs, which is permanently frozen to some degree.
