"#define bool bool" says QtCreator when I find bool - I tracked it in boost :: asio

Question

I noticed that it is boolhighlighted in a different color than other types in QtCreator:

This only happens when certain headers are included, in the end I tracked it to <boost/asio.hpp>. The QtCreator code inspector does not seem to be able to track the definition manually. My version I'm using is Boost 1.59.

Is there any purpose for this? I do not mind, but it’s rather strange to define something the same thing, more than that bool.

#define bool int
// The next line would change the previous definition
#define bool bool
