Faced when trying to build static-web-server:
The following warnings were emitted during compilation:

Hello.
According to Posix, that SI_MESGQ should be available. Can you somehow find out if OpenBSD just misses that thing (which is related to functions like mq_notify), or if it's available in some other header? I don't have that OS around and I would like to decide on how to fix that problem based on the info.
It seems like OpenBSD is missing that: boostorg/test#231
OK, if this is a good enough fix for Boost, it should be good enough for this crate.
Can you test #147 before I merge it?
I ran cargo test ; cargo build on openbsd-compile-fix branch, it works. Thanks!
Released to crates.io as 0.3.16. Thank you.
