HPPA support is not gone from Guile; and indeed it's good to hear from you :) I wasn't sure there were any IA64 users remaining. Initially in Guile I planned to use GNU Lightning, in part because of its great platform support. However it turned out to not be the right thing, and reluctantly I ended up doing something that was more like a rewrite than a refactor. In that context I personally don't have the budget to write the IA64 backend. So, Guile 3 still runs on IA64, just without JIT support. If someone would like to write an IA64 backend for Lightening, I would be happy to accept it :) The beginnings of one are there in the git history. Andy
