Could you maybe also send the output of `./configure`? We do have a check in "configure.ac" that tries to find out whether your system has `inet_ntop()` or not. Maybe it is misdetecting the availability of that function on your platform and thus declares the `NO_INET_NTOP` variable, which causes us to pull in compat code.

Out of curiosity, did you try running `make` without first running `./configure`? Many platforms should work alright without having to run autoconf first, but given that your platform is a more on the esoteric side I wouldn't be surprised if things didn't work there.
