+Subject: [PATCH] fix unused attribute in func definition
+
+UNUSED is for wrapping variable decls, not for variables in a function
+definition.  It will insert a semi-colon into the mix which makes clang
+upset:
+x86_64-cros-linux-gnu-clang  -DHAVE_CONFIG_H -DSYSCONFDIR=\"/etc/mtools\" \
+	-DCPU_x86_64 -DVENDOR_cros -DOS_linux_gnu -O2 -pipe -O2 -pipe \
+	-march=x86-64 -msse3 -g -fno-exceptions -fno-unwind-tables \
+	-fno-asynchronous-unwind-tables  -clang-syntax -Wall \
+	-fno-strict-aliasing -I.  -I.  -c mainloop.c
+mainloop.c:89:15: error: expected ')'
+int unix_loop(UNUSED(Stream_t *Stream), MainParam_t *mp, char *arg,
+              ^
+./sysincludes.h:106:47: note: expanded from macro 'UNUSED'
+                                              ^
+
+Arguably this should fail on gcc too, but it doesn't today.
