For what it's worth, I don't think the proposed fix is right. Slang
would end up using h_addr instead of h_addr_list if compiled with
glibc versions from before 2.8, and I don't think that was intended.
The #ifndef h_addr branch is only needed for compatibility with 4.2BSD
--- already in 4.3BSD, struct hostent has an h_addr_list field and an
h_addr compatibility macro --- so it might be better to just get rid
of the code that uses the old interface. If a minimal diff is the
goal, something like the following should work:
diff -u a/modules/socket-module.c b/modules/socket-module.c
