Proceeding on the (probably bogus) assumption that the reason I don't have a
src/sys/arch/sparc/rcons directory is that it's made it from something
experimental to become normal code (in sys/dev/rcons) so I boldly commented
out the following from file.pmax, ran config.netbsd and proceeded to build:

[By the way, just as a side issue, how *would* someone that had been building
for awhile know if a directory they were depending on moved, does SUP delete
directory trees too?? <ack.. scary thought>]

(I commented these out)

#file   arch/sparc/rcons/raster_op.c            rcons
#file   arch/sparc/rcons/rcons_kern.c           rcons
#file   arch/sparc/rcons/rcons_subr.c           rcons
#file   arch/sparc/rcons/raster_text.c          rcons

This got close, but no cigar. Though the number of files I had to mod to add
some casts to keep the compiler happy dropped to 1 (good deal!)
(src/sys/arch/pmax/tc/if_le.c, line 283 if anyone's counting :)

I still get some unresolved symbols when the final link is done:

(Since the undefined symbols point squarely back to the rcons stuff, I seem to
be in a loop thrashing around this same problem no matter what I do...)

Thanks,

(ps, still can't get through to [sup, ftp].netbsd.org tried several times over
a period of several hours last night and this morning.)
