Per the discussion in the link, specifically "All the supported languages except C and C++ are second-class citizens.", I'd seriously consider writing off everything except C, C++, and any language where someone steps up to actively support their language going forward. Slice autotools down to 32-bit & 64-bit UNIX systems in the last couple of years (bearing in mind that if you start that today, by the time it is finished it will constitute support for the last 3-5 years)... or even all the way to current systems for the parenthesized reason... for C and C++. Would probably also call it "Autotools 3" and slice away anything else that doesn't seem useful, on the grounds that 2.7 isn't going anywhere. If in doubt, slice it away and see what people say when you release 2.99.01. This probably takes it down to something not so enormous to carry around. It seems like other languages are all going their own way. Maybe that's bad, maybe that's good, most likely it's a complicated combination of both, but most importantly, there's nothing Autotools can do to stop it at this point, so you might as well roll with it.
