I'm not quite sure what the canonical declaration style is, -lib/- path or -stdlib/-stdpath. I guess the former will work better for Pd's own default setup.
I should say this is true since 0.50 or so. Before that, -stdlib/- stdpath was the common thing to use.
What would be then the canonical now, no "-std"? I can change that easily in my patches, but would be good to have it confirmed.
