PT_READ_U and PT_WRITE_U are the 'old way' of getting and setting
process registers.  not particularly 'clean,' nor particularly secure.

the new way is with PT_GETREGS and PT_SETREGS (and PT_{GET,SET}FPREGS).

Adding PT_READ_U and PT_WRITE_U to ptrace.h won't help; nothing will
actually be implementing them, anyway.

you should change infptrace.c to use the new functions.  (If you do
so, you might mail the list with a copy of the diffs.)
