! 31: * Support getaddrinfo() on platforms that don't have it.
! 32: *
! 33: * Note: we use our own routines on platforms that don't HAVE_STRUCT_ADDRINFO,
! 34: * whether or not the library routine getaddrinfo() can be found. This
! 35: * policy is needed because on some platforms a manually installed libbind.a
! 36: * may provide getaddrinfo(), yet the system headers may not provide the
! 37: * struct definitions needed to call it. To avoid conflict with the libbind
! 38: * definition in such cases, we rename our routines to pg_xxx() via macros.
! 39: *
! 40: * This code will also work on platforms where struct addrinfo is defined
! 41: * in the system headers but no getaddrinfo() can be located.
