I know set is bool. But that should not matter, code is okay and
compiler will do the right thing:

pavel@amd:/tmp$ cat delme.c
#include <stdbool.h>

void main(void)
{
  bool a = false;
    int b = a;
 }
 pavel@amd:/tmp$ gcc -std=c99 -Wall delme.c
    delme.c:3:6: warning: return type of âmainâ is not âintâ [-Wmain]
     void main(void)
           ^
	   delme.c: In function âmainâ:
 delme.c:6:7: warning: unused variable âbâ
 [-Wunused-variable]
	      int b = a;
	             ^

Best regards,
