Currently, lclint has a non-free license listed in the package, and it is in the non-free section. However, as reported in Bug#43590, it is actually under the GNU GPL, as downloaded from http://www.sds.lcs.mit.edu/lclint/ Are you planning to fix this and upload into main for potato? I would really like to have a free lint in potato.
