That sounds like a challenge! :-)

That is a WIP and COMPLETELY UNTESTED patch to turn on UFS1_AND_UFS2
and it ends up with 7 bytes free. I wouldn't install this on anything
but a spare floppy disk yet.
I have a couple of nastier versions that have ~30+ bytes free but
I'm pretty sure I broke the pathname lookups there. And for that matter,
I'm not even sure if -fomit-frame-pointer is compatable with -mrtd... If
not, oh well. :-)
Cheers,
-Peter
