Maybe someone here can help me spot the error....

I'm using GNAT 3.12p on Win98 and trying to get the Winsock binding to
work successfully. I've got a simple program here which illustrates the
problem. Just to illustrate, I've got a simple call to the "Socket"
function which parallels examples I've found in "Windows Sockets Network
Programming" by Bob Quinn & Dave Shute. I've successfully got the Ada
version of the call to compile, link and run. The problem is that the
function consistently returns INVALID_SOCKET and I can't figure if I
have something wrong with the parameters or am missing something
obvious.

The code below illusrates the problem. If you can spot my error, I'd
appreciate the help. (BTW: If you reply to this message, please remove
all the anti-spam chaff in my return address.)
