Thus, the warning also needs fixing. Since the same behavior will occur if the
user directly or indirectly includes stdbool.h.
A testcase:
# 1 "false.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "false.c"
# 1 "sys.h" 1
# 2 "sys.h" 3
# 2 "false.c" 2
int * foo() {return
# 2 "false.c" 3
false
# 2 "false.c"
;}
# 1 "nonsys.h" 1
# 4 "false.c" 2
int * bar() {return false;}
