The copyright years don't appear right to me. Either 2001-2013, taken
from gdb/mips-linux-nat.c, or just lone 2013 seem more appropriate to me,
but http://www.gnu.org/prep/maintain/maintain.html does not appear clear
to me on it -- would someone please step in and explain what GDB's usual
policy has been here?
Can you please reorder the sequence of functions moved here to match the
original one in gdb/mips-linux-nat.c?
Also, anyone: do we still aim to maintain gdb/config/djgpp/fnchange.lst?
If so, then on what basis -- ad hoc? ChangeLogs show most recent random
additions last year only and files appear to be missing from the listing.

Same copyright year concern as above.

You actually need to keep that <asm/ptrace.h> inclusion, per GDB's coding
requirements (see gdbint.info).
Please resend with the changes requested.
