Link error with VC++ linking to libpq.lib

Perhaps I asked at the wrong time, so let me try again.

I'm using Visual Studios C++ Express 2008 on Windows 7 with the "standard" (pre-packaged) 64-bit Windows distribution of PostgreSQL v.9.0.4 and I am having unresolved refs when linking to libpq.lib. The relevant elements of my program are:

#include "stdafx.h"
#include "libpq-fe.h"
using namespace System;

int main(array<System::String ^> ^args)
{
...

char *pghost = "localhost",
*pgport = "5432",
*pgoptions = NULL,
*pgtty = NULL;
char *dbName = "mydb";
PGconn *conn;
/* make a connection to the database */
conn = PQsetdb(pghost, pgport, pgoptions, pgtty, dbName);
...
)

Linking against libpq.lib in the postgres "lib" directory, the error I get is:

DBTest.obj : error LNK2001: unresolved external symbol "extern "C" struct pg_conn * __cdecl PQsetdbLogin( ...

So, how do I fix this and get this thing to linik without error?

On a possibly related topic, is it possible to link to static postgres libraries and not require the use of the .dll's?
