System File Protection again? Are you measuring real TCP connections or
local connections, using memory-mapped files through IPC in Windows?

Then I'm inclined to think that you're exercising really the
hostname:/fulpath/gdbfile.fdb
syntax. Just trying to be sure.

For what I see from the makefiles, we are linking against
wsock32.lib
and in the "remote" directory, the file inet.c has a function named
alloc_port()
that does this:

#ifdef WIN_NT
if (!INET_initialized)
{
WORD version;

version = MAKEWORD (1, 1);
if (WSAStartup (version, &INET_wsadata))
[snip]

We also seem to be including winsock.h only.

According to my MS Platform SDK, we should include
winsock2.h instead, do
version = MAKEWORD( 2, 2 ); instead
and link to Ws2_32.lib instead.

Better, we could do
version = WINSOCK_VERSION;
that ensures latest version is set depending on the header. I can see
winsock2.h both in the include dir of MSVC 6.0 and in the include dir of the
classic BC++ 5.02 (circa 1997), too and I remember I used it a couple of
years ago, so v2 is not a W2K thing, but the thing we should be using now.

Hmmm, who said we are outdated? :-)
Someone sporting the precision of a surgeon should fix the relevant places.
I don't volunteer.
