> But even ignoring my projects that involve multiple languages simultaneously, I still regularly use several languages in total, even if only one per project. So having a build system that's independent of the language is still highly desirable. Ah, that’s a difference between us: I prefer to always use one primary language, and all others are secondary languages selected per-project. So it makes sense for me to just use a system built in my primary choice. > My answer to that is "no, never", of course. Agreed, too! In principle upgrading the compiler should have no effect whatsoever on correct, portable programs. OTOH, there sure do seem to be an awful lot of incorrect and unportable programs out there!
