I've been working with christos on the sparc svr4 emul problem,
and we've narrowed it down to a compiler/toolchain issue.
I had noticed a while back that the problem only happens when the
kernel is ELF, a.out kernels work fine.  as a goofy experiment,
I tried converting an a.out kernel to ELF with objcopy, and
I was completely amazed to find that this produced a working kernel,
svr4 emul and everything.  both of these compilers are egcs-1.1.2,
I just updated my a.out gcc/as/ld to the current gnu/dist stuff and
svr4 emul still works.  anyone have ideas on how to proceed from here?
