Mark,

I've created the branch: cagney_convert-20030606-branch and committed 
the attached.  It's different from the original in the following ways:

- REGISTER_TO_VALUE and VALUE_TO_REGISTER take the full ``struct value'' 
instead of ``struct type'' and a ``void *buf''.  Those methods are now 
entirely responsible for converting a register to/from the specified value.

- Adds the possibly contraversal put_frame_register method.  It turned 
out that at least three functions contained the code sequence: find 
REGNUM's true location, store the value in that location.

Feel free to try to get the i386 stuff working.
