invalid use of incomplete type ‘struct ares_addrinfo_hints’

[t348575]

I'm trying to build drogon but I'm getting a compilation error in trantor. I followed the standard environment setup and build steps provided in the docs (using cmake). A separate clone of trantor on the latest release tag gives the same build error.

My environment:
OS: debian (WSL) (kernel 5.15)
Compiler: Tried both GCC 12 & Clang 16
