// DNS system header files are a mess!
// <resolv.h> includes <arpa/nameser.h>. <arpa/nameser.h> is using
// 'u_char' and includes <sys/types.h>.  Now the problem is that
// <sys/types.h> defines 'u_char' only if __USE_BSD is defined.
// __USE_BSD is defined in <features.h> if _BSD_SOURCE is defined.

// 2) need to specify POSIX thread interfaces explicitly in glibc 2.0
