you should add wsock32.lib to list of libraries your driver will be
linked with. you should also add psqlodbc.rc and psqlodbc.def to your
project. please read readme.txt (it should be in the same directory with
ODBC driver sources)

I have built ODBC driver from CVS tree with Visual C++ 6.0 yesterday
successfully and now Visio successfully reverse-engineers our database
scheme (with foreign keys). That's really cool.
