HAVE_GETIFADDRS is still used, for example here: https://github.com/dotnet/runtime/pull/71943/files#diff-404dd4500e99144ae93b6753065902099e05f7fc7ef19834d0d6e152ed0e6b45R253

@simonrozsival that is part of System.Native, not mono. It has its own check:

runtime/src/native/libs/configure.cmake

Lines 139 to 141 in f249dc7

check_function_exists(
getifaddrs
HAVE_GETIFADDRS)


/* Have struct ifaddrs */
#cmakedefine HAVE_IFADDRS 1
