i've commited a partially working compat/sunos32 directory to netbsd-current.
   simple programs that use read/write/open type calls seem to work fine, but
   real programs like tcsh and any compiled sunos program seem to dump core
   quite earlier for more.
   
   
   so the first step is done.  now we just need to make it all work :-)



OK, most programs seem to work now.  i haven't tried, eg, netscape, but i
plan on getting to that soon.  `tcsh' mostly works.  it has a problem that
appears to be the same as a netbsd/sparc `tcsh' has under compat_netbsd32,
and as the sunos32 code uses the netbsd32_execve() function, i guess the
problem is in there somewhere.  besides that, `tcsh' works just fine now.


i encourage people who use sunos4 programs to test them out on sparc64
(64 bit mode!) to see what happens.
