   Because <sys/user.h> used to and no longer does.  If you prefer I can
   define the structure (pt_regs) in the file itself.

Ah, I missed `struct pt_regs'.  Hmm.  On the i386 ptrace(PTRACE_GETREGS,...)
doesn't return a `struct pt_regs'.

   <sys/user.h> now uses a "struct user_regs" instead, but we can't use
   that without requiring glibc 2.2.x.

I'd use elf_gregset_t instead.  Should work with all versions of glibc
as long as you include <sys/procfs.h>.  Looks like there's quite a bit
of redundant code in arm-linux-nat.c.  Feel free to clean it up a bit :-).
