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. ;-) > + * threads.h (scm_i_thread): New IA64 fields: > + register_backing_store_base and pending_rbs_continuation. This breaks ABI compatibility on IA64, but if Guile wasn't usable on IA64 (was it?) that's probably not a problem. > + void scm_ia64_longjmp (jmp_buf *, int); Add `SCM_API' at the beginning and `SCM_NORETURN' at the end.
