Summary: Failure with 08.02.0002 / 8.1.3: Cannot read ints of that length

Initial Comment:
I'm trying to get psqlodbc running on OpenBSD 3.9 amd64 and i386 with PostgreSQL 8.1.3, but iodbctest fails. No problems with 8.1.2.

Apps/libs:
iodbc-3.52.4
postgresql-8.1.3
psqlodbc-08.02.0002

My configuration:
$ cat .odbc.ini
;
; odbc.ini
;

Message:
Uhm! I got multiple errors.
First i just found out what was wrong on i386... i need to use ``Servername'' instead of ``Server'' or ``Host'' in odbc.ini.
So my guess that ``server='' in the mylog shows the problem was right, leaving the question wether this is driver dependant.
But on amd64 / PostgreSQL 8.1.4 even with the suggested fix the error remains the same.

Message:
Please change the line 77 in psqlodbc.h

#define Int4 long int
to
#define Int4 int
.
