So this means that there *was* a change according the PPP in 1.3.2?

Hmmm ... this depends on your recommendation, Simon. We're using this in 
a production environment (which is not really working according to the 
issue above) ... if there are definitely some fixes which also covers 
this problem, i may give it a try. In that case, what files do i have to 
replace? ppp.c and ppp.h? I don't want to change the rest of the stack 
to a non-stable version ...
