Hello, I'm writing a C program and having a question. My program is intended to run under stable/9, releng/9.3, stable/10, releng/10.2, releng/10.3 and sometimes current. Stables are not always up to date. I'd like to check if getaddrinfo(3) supports AI_V4MAPPED using something like "#ifdef" or "#if" macros because it is not necessarily implemented[1]. Probably I can use __FreeBSD_version for that. Is this way good? If so, > #if __FreeBSD_version > __VALUE__ what the __VALUE__ will be?
