Author: hselasky Date: Wed Jul 2 08:49:06 2014 New Revision: 268138 URL: http://svnweb.freebsd.org/changeset/base/268138 Log: Add support for empty data sets. Data set begin and end pointers should resolve to "NULL" when not present. This is done by declaring the data set begin and end symbols as "weak".
