Hmmm... here is no error. Just promotion and a misnomer.. ;)
Why do you think it comes from pluto?

It seems that (__KERNEL__) is not defined  once ((RTAPI is not) or (SIM is) 
defined) .
maybe the clue  lies here...
https://github.com/jepler/linuxcnc-mirror/commit/78015346686fbb7f530449b01ca3dee2ad28dbfd#diff-5c08d5c249a037c2be98e595240e3eefL209

it looks like there is some mismatch with gentoocnc, userspace, RTAI etc.

but it's just a assumption.
