Jon, I think you are solving a problem you don't really need to solve.
Unless the third party explicitly set the AH_SOMETHING_DMB from config.h
the value won't get set from urcu/config.h and thus such user won't be
So this scenario is so hypothetical that it probably won't happen.
(The obvious solution would be to have urcu/arch.h generated from
instead of modifying the contents from urcu/config.h #defines that can
overriden by third party config.h.)
I think there's nothing the urcu folks can do for us, but thanks for
and trying to help us.
