Thanks a lot for fixing this! It just missed 1.8.5 my a few hours (my
fault). Hopefully distributions will apply the patch by themselves
until we release a new version...
Thanks also for the nice explanation. I must confess I didn't grasp
everything (especially since I'm not familiar with IA64 and its RBS
thing), but I'm confident you did the right thing. ;-)

This breaks ABI compatibility on IA64, but if Guile wasn't usable on
IA64 (was it?) that's probably not a problem.

Add `SCM_API' at the beginning and `SCM_NORETURN' at the end. The
latter should fix this:

Thanks!
