Hi Ilija,

We actually did some work on this at the end of last year, but then it got lost
in amongst other things.

We have a patch I'll attach shortly that removes the test. Neither of us who
have worked on this are in any way ppp experts, however we felt it was just not
possible to port the test to the new version of lwip so we have removed it.

We see no warnings (CodeConfidence tools GCC 4.3.2). If you give details we can
try to take a look at them.
