Hello!

The icmp example provided with the asio-library in 1.40 throws a system 
error with code 10044 "The support for the specified socket type does 
not exist in this address family." when compiled with _WIN32_WINNT 
0x0500 and executed on an Win2000 machine.

The error comes from the gai_echeck()-function in socket_ops.hpp which 
is called with family AF_INET and socktype SOCK_RAW:

inline int gai_echeck(const char* host, const char* service,
     int flags, int family, int socktype, int protocol)
{ ....
   switch (family)
   {
   case AF_UNSPEC:
     break;
   case AF_INET:
   case AF_INET6:
     if (socktype != 0 && socktype != SOCK_STREAM && socktype != SOCK_DGRAM)
       return EAI_SOCKTYPE;
...

I have attached the callstack for call to gai_echeck()
I'm using Visual Studio 2005 and boost 1.39 (although the example is 
from boost 1.40)
I changed the return value of gai_echeck() back to 0 in the debugger and 
then the rest of the icmp(ping) example ran without any apparent problems.

Best regards,
Wolfgang
