Cygwin does not support IPv6 yet. Check for something you can #undef to disable IPv6 in the app, or check the IPv6 configure tests. You could also grep for inet_ntop() in the source and see if it's guarded by any #ifdefs - if not it assumes IPv6 support which is not present, and you'll have to adapt it accordingly. (Disclaimer: I have no idea what "lam-mpi" is or does.)
