the stan test suite includes model
src/test/test-models/good/deprecate-increment-log-prob.stan which compiles, but generates many warnings:
Warning (non-fatal): increment_log_prob(...); is deprecated and will be removed in the future. Use target += ...; instead.
this is causing the integration test to fail. I don’t think anything I’ve done on my branch should change this - has anything in the makefile changed?
