MSDN says it's available since Windows 95, but the prototype isn't 
included unless
_WIN32_WINNT >= 0x0501
0x0501 means Windows Server 2003, Windows XP. Previous windows didn't 
include a built-in
getaddrinfo()

They're completely logical. It's include madness (i'm using the 
mingw's). My header says: "These are not
exported from any known w32api library.  Are they implemented as macros 
or inline finctions?"
Well, it *is* an inline function on windows Ws2tcpip.h Rechecking, newer 
headers do set it as inline, so
we can probably leave gai_strerror.c out.
