--- Comment #7 from Jan Hubicka <hubicka at ucw dot cz> --- > Honza, did you get anything working? Sorry, I am at Mountain trip till 6th of September, so I do not have much chance to hack. Will take it as priority afterwards. I think cleanest approach would be to lower these calls into sequence of warning/error builtin and call.
