1>oknotmp.obj : error LNK2020: unresolved token (0A00000D) "int oknotmp::liczby" (?liczby@oknotmp@@$$Q3HA)
1>okno2.obj : error LNK2020: unresolved token (0A000007) "int oknotmp::liczby" (?liczby@oknotmp@@$$Q3HA)
1>okno2.obj : error LNK2001: unresolved external symbol "int oknotmp::liczby" (?liczby@oknotmp@@$$Q3HA)
