Neither, I stumbled over this while working on a modified version of
perf tools. The interface definition of util/parse-events.h contains
type bool and u64, but both are not defined. Thus, including
parse-events.h independently of other header files will raise this
compile errors. It took me some time to figure out what happened so I
think it is worth fixing it.
