Ho lokolloa ha GCC 13 compiler suite

Ka mor'a selemo sa nts'etsopele, ho lokolloa ha mahala GCC 13.1 compiler suite e lokolloa, tokollo ea pele ea bohlokoa lekaleng le lecha la GCC 13.x. Tlas'a leano le lecha la linomoro tsa tokollo, mofuta oa 13.0 o sebelisitsoe nakong ea nts'etsopele, 'me nakoana pele ho lokolloa ha GCC 13.1, lekala la GCC 14.0 le ne le se le ferekane, moo ho tla thehoa tokollo e latelang ea bohlokoa ea GCC 14.1.
