As I wrote in my email, I can see B_TRUE and B_FALSE are defined as boolean_t in sys/cddl/compat/opensolaris/sys/types.h But I can't see that boolean_t is defined anywhere in the included headers as long as KERNEL is not defined.
In sys/cddl/compat/opensolaris/sys/types.h, there is:
typedef enum { B_FALSE, B_TRUE } boolean_t;
This line defines the boolean_t type. Maybe the type itself is never
used, but only the enum values. Sort of like a an anonymous enum in C++.
