Sparc should be supported, as afs already works on both sparc-solaris and
sparc-linux. There may need to be some assembler syntax and makefile
hackery to get it building.

It's not pthreads, but I do have an alternative to the existing lwp
implementation that should be a whole lot more portable that what we have
now. It makes use of the getcontext/makecontext/setcontext functions from
The files are in the afs request tracker.
(https://grand.central.org/rt/Ticket/Display.html?id=1280). You will want
lwp_susv2.c, lwp_private.h and lwp-opaque.patch. Apply lwp-opaque.patch,
drop in lwp_private.h, and replace lwp.c using lwp_susv2.c. Lastly, edit
the makefile and remove references to process.[coS] for the relevant
platform(s). If you do use this code, please reply to the ticket with any
successes/failures you encounter. If this code gets tested, it's likely to
be folded into an actual release someday. E
