Hi Michael -
How did a fundamental bool type (which, if I'm not mistacking, is a c++
type) got into a kernel object?
I think that the answer is to map it to TYPE_CODE_CHAR regarless, so
that the size would be properly handled in structs. c++ seems to be
mapping a bool to a char from a size perspective.
