Bleah, to that part. 2.71 isn't even available on Fedora Core 35 which was released 6 months ago. I'm afraid this will break lots of builds in not-very-old environments. I'm inclined to look into whether I can just replace the obsolete macros to shut up the warnings for now, does that seem reasonable? And then bumping the 2.50 minimum to the 8-year-old 2.69 is probably wise ;) Thanks, -Eric
