If I remember correctly, I tried to remove epdisc if multilink is not 
enabled, but the required work does not justify the 22 bytes memory 
gain. Especially because go->neg_endpoint is used in several places in 
lcp.c, often explicitely outside of the PPP_MULTILINK scope, there is 
probably a very good reason to be done this way in pppd.

Yeah, that was just a though, of course it does not work because extern 
"C" only concerns symbols export.

Anyway, I pushed your patch in the git branch a few hours ago ;-)
