Ideally, you should have no uses of any library functions in your
Epiphany code, so this would not matter.  Your code should do
computation only.

With bcrypt, we're using internal.ldf, but the only library function
we're getting linked in is memcpy(), which is tiny and affordable.  In
your case, since you have TMTO, you'll want to avoid even things like
memcpy(), in favor of your own special-case code (could be smaller).

Confirmed, corrected.  The network tunnel didn't come back up correctly
after a reboot.
