+Subject: [PATCH v2] libopkg: Use libgen.h to provide basename API
+
+Also ensure that copy of filename is passed into archive_entry_set_pathname
+so it can be operated upon by posix basename which expect non-const
+character pointer as input.
+
+This became evident with latest musl where basename declaration was
+dropped from string.h [1]
