+Subject: [PATCH] Remove unused file-scope variables
+
+Crc32 (zm.c), ztrans (lrz.c), vpos and Beenhereb4 (lsz.c) are only ever
+assigned, never read: Crc32 is a leftover display flag superseded by
+Rxframeind, and the other three no longer feed anything. clang 23 adds
+-Wunused-but-set-global, enabled by -Wall, so the default -Werror build
+now fails:
+
+  src/zm.c:37:12: error: variable 'Crc32' set but not used [-Werror,-Wunused-but-set-global]
+  src/lrz.c:111:13: error: variable 'ztrans' set but not used [-Werror,-Wunused-but-set-global]
+  src/lsz.c:97:13: error: variable 'vpos' set but not used [-Werror,-Wunused-but-set-global]
+  src/lsz.c:132:12: error: variable 'Beenhereb4' set but not used [-Werror,-Wunused-but-set-global]
+
+Remove them and their stores.
