ODBC problem with R13B01 in OpenBSD 4.5 amd64

[Nikolay Epifanov]

Hi,

while trying to connect I get:

Erlang R13B01 (erts-5.7.2) [source] [64-bit] [smp:4:4] [rq:4]
[async-threads:0] [kernel-poll:false]

Eshell V5.7.2  (abort with ^G)
1> odbc:start().
ok
2> {ok, Ref} = odbc:connect("DSN=pc-backend", [{scrollable_cursors,off}]).

Same error for both iodbc and unixODBC.
Actually odbcserver exits in (lib/odbc/c_src/odbcserver.c:1646)  WIN32
version of connect_to_erlang after receiving ECONNREFUSED for "connect(sock,
(struct sockaddr*)&sin, sizeof(sin)". This WIN32 function enforced with
#define USE_IPV4. I switched to UNIX one and at least connects and queries
started working. The patch that made this change is
http://www1.erlang.org/pipermail/erlang-bugs/2007-October/000486.html
Why does the WIN32 function have to be used? Is it ok to use UNIX version?
