  BTW, you traded one failure for another, now PIC is broke
  for ultrasparct3 builds, because now in invert_limb.asm we're

  which will only work on 64-bit static builds.
  
I know.  It was easier to go back to the previous state for all assembly
files first.

The code is now correct in the repo, I think.  I might have introduced
other bugs, but I ran what I hope was adequate tests on both a Solaris
and a GNU/Linux system.

I might have reverted some TYPE statements.  These should be put back.
