the following two (potential) problems:
1) winsock2.h must not have been included before this symbol
is set (I think).
2) There may be some _reason_ for all prototypes not being
available with the default settings. Such as if some APIs are
not available on older Windows hosts. However, getaddrinfo
(which need >= 0x0501) should be available on Windows 95 and
later, according to:
