Not sure, if this is even intended. Just reporting it to be sure.

Okay, it seems like OpenBSD's netdb.h doesn't contain those flags although POSIX requires it.

I guess then this more or less an non-issue for haskell-socket? Feel free to close, if so.

I just ran into this very problem myself. Defining AI_ALL and AI_V4MAPPED as 0x0000000 allowed me to compile it.

Running the test suite we get some failures, that I haven't looked into too much yet.
