Severity: wishlist The 'mksintalldirs' script has been by long superseded by "install-sh -d", has already deprecated in the documentation, and already removed in AUtomake-NG. I'd like to remove it in future Automake versions.
However, we must first find a viable way to non-fatally deprecate it with some form of runtime warning. I haven't yet thought in any detail about how that; I'm just opening this report to ensure the question won't slip through the cracks. Regards, Stefano
