Hi, has anyone tried to build the crosscompiler host=1386, 
   target=sparc64 ? 



this should work if you enable this line in cross/binutils/Makefile:

#ENABLE_TARGETS+=       sparc64-elf

and disable this line in cross/sparc64-netbsd/Makefile:

BROKEN=                 kills sparc-netbsdelf support


note the caveat ... and note that the 64bit compiler is not
entirely stable.  (see port-sparc archives for messages from
eeh@ for details on this).


and you might find this `cross.sh' useful.  it contains
documentation for it's use in a cross compile environment.
