I looked over the warnings and they all seem to arise from casting
pointers to or from SQLUINTEGER.  I presume the latter is meant to
be 32 bits, so the failure on 64-bit machines is hardly surprising.
It's not clear to me what the appropriate fixes are --- fixing this
appears to require changing the APIs of the functions involved, and
I don't know what the ramifications would be.

I've attached a list of the current warnings (current as of 08.01.0102
sources).

The two warnings in PGAPI_SetConnectOption definitely look like crash
cases to me.  The others might be fixable by changing, eg,
            if ((SQLUINTEGER) Value == SQL_OV_ODBC2)
to
            if (Value == (PTR) SQL_OV_ODBC2)
