i dont know if things would work quite right- config has certainly
changed betwen 1.3 and 1.4, and probably there some gcc idiosyncracies 
that will make it barf on the 1.2 stuff..

hmm. it might be worth the effor tin making it work to see directly whats
from the compiler and whats just the kernel.. :)

ah, but it it only running tahoe! th eonly netbsd/vax machine i have running
right now is the 4000/60! (well, and a VLC somewhere, but it's on loan
to a friend several thousand miles away, and not on the net) 
so if you want to compile anythign under tahoe, feel free, the machine
is open to all.. (telnet to, log in as vax, then 
guest/guest, or if you have an account, log in at that point , or sloer 
machine/faster network,, guest/guest) 
Over the weekend i can put the 4000/60 up for general use, but its only 
got 8mb of memory so far.. :(
