-Subject: [PATCH] sm3600.h: Fix build with standard C23
-
-bool, true and false are keywords in the standard C23 - the sm3600
-backend defines them on its own, which is forbidden with the new
-standard.
-
-The patch adds ifdef guards for the affected typedef - the old code
-will be used for older standards, C23 will define TBool as bool.
