They currently do nothing, since the getter functions don't actually capture (copy) the strings but merely return pointers to read-only strings. But the calls are placed here for consistency, because if one day the getters' implementation is changed so that strings are captured, it would then be needed to free the allocated buffers. In addition, fix a buggy call to INF_GetData() -- should be instead INF_GetDataField() -- in AddSectionToCopyQueue(). svn path=/branches/setup_improvements/; revision=75516
