Thanks for pointing Robert.
What we are going to do is to remove all references to the bool type,
replaced by int (which is at the end the type used by C users).
Then, for axl and vortex, we define the API convention that false is 0
and true is 1. This will move us from having troubles in other platforms
since the code will check/expect to receive those values.
This will make c++ users to use 1 and 0 values to manipulate boolean API
(as they are doing at this point), avoiding to give the impression that
the c++ bool type can be used directly.
If someone else have some comment or suggestion, it would be really
