Unknown 8d1af19 for CDRIVER-4227 introduced -D_XOPEN_SOURCE=700, which specifies POSIX 2008. When adding that to PHPC's CFLAGS, I now see errors that several DNS constants and symbols are no longer defined. The Conforming To section of h_errno(3) states:
POSIX.1-2008 removes the specifications of gethostbyname(), gethostbyaddr(), and _h_errno_, recommending the use of getaddrinfo(3) and getnameinfo(3) instead.
Seems relevant, but I'm not sure why libmongoc didn't require additional changes (mongodb/mongo-c-driver#910) when instituting that change. Build errors follow:
