Postgres 8.3.3 & MSVC2005 (full edition)

[el dorado <do_ra_do@xxxxxxx>]

Hello.
Have I an opportunity to get working dll using MSVC2005 (full edition) for compilation at all?
I just tried to compile the following code. This is full text. Project options are below in the letter.
-----------------------------------------
#include "postgres.h"
#include "fmgr.h"
#include "executor/executor.h" 
#include "utils/timestamp.h"
#include "utils/builtins.h"
#include "utils/formatting.h"

#define BUILDING_DLL 1

#ifdef PG_MODULE_MAGIC
PG_MODULE_MAGIC;
#endif

PG_FUNCTION_INFO_V1(add_one);
         
Datum
add_one(PG_FUNCTION_ARGS)
{
    int32   arg = PG_GETARG_INT32(0);
    PG_RETURN_INT32(arg + 1);
}
-------------------------------------------------------
CREATE FUNCTION "service"."add_one"() RETURNS integer
     AS '$libdir/my_dll', 'pg_finfo_add_one'
     LANGUAGE C STRICT;

Result:
Query OK (0,11 sec)
Return Value: 32593236

Even if I do the following:
PG_FUNCTION_INFO_V1(add_one);
         
Datum
add_one(PG_FUNCTION_ARGS)
{
    PG_RETURN_INT32(10);
}

I get the same result - Return Value: 32593236

Have I forget some important option? Or I can't use the FULL version for compilation at all - only express edition?

By the way - there is a directory 'D:\pgsql83\include\server\port\win32_msvc'. But I can't use it instead of 'D:\pgsql83\include\server\port\win32' (should I ?) - there is an error due to lack of file 'netdb.h' and some others in this directory.


Thanks in advance, Marina.
