Those would appear to be just cases where the code hasn't been compiled
with the various options turned on an off - this is one of the reasons
why so many compile time options can be troublesome, but they do help to
keep the compiled code small.

The solution really needs someone who understands the PPP code though,
which I'm not, and they're a bit thin on the ground at the moment.  Any
volunteers to help fix this?
