I am looking at a 1989 paper by Beetem & Beetem [1] but then it was called Galaxy.. I agree "much older" might be a bit.. much. Haha.

EDIT: Joking aside, I would love to hear a compare & contrast between Galaxy/GalaxC & LX/XL, though!!

EDIT2: and via that first link, I think you can get to a full source code distribution compile-able with C on 32-bit Linux. Might have its own woes like LLVM hosting, but those might also be more solvable as part of a 64-bit port.
