Arg.  It looks like I must have added another few instructions
somewhere, and triggered the same size-increase that I talked
about in the "Adventures with gcc: code vs object-code size"
thread on the freebsd-hackers.  In that case, adding 40 bytes
of new instructions to one routine in ps.o caused /bin/ps to
jump by 3940 bytes.

As long as I had avoided whatever that threshold was, I was
able to keep the size down around 27000 bytes.  And that was
for a version which *included* the -R, -s, and new -g options.
Man that's annoying, I had been doing so good with it...
