I'm sure I spotted something that implied that gcc already generated
8-byte aligned stack frames for SPARC (to do with interworking with
code compiled with one of the sun compilers).
So maybe it won't be too hard - if you know how gcc works!
(I've a strongarm/sidekick system here I might try to port netbsd to,
probably work better than the vxWorks port - less frustrating anyway)
