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.
