I notice that (void)INTCONbits; fixes the _INTCONbits problem.
As you would expect, I do not see the _cinit error with a program
containing data.
I do not wish to impact real development. If this problem I am
having seems to be unique to me, please move on with something of
more importance. Please let me know if there is real help I can
provide.
