Borland doesn't like Nasm .obj files?

[el-half]

I assemble the following:

global _printhello     ;exports

SECTION .text

_printhello:
mov ah, 09h
mov edx, string   ;32-bit register usage is necessary for win32 obj file
int 21h
int 20h

SECTION .data

string db 'Hello world!$'

to a win32 obj file:
C:\>nasmw -f win32 phile.asm

This produces a .obj file phile.obj
Because borland c++ 5.5 doesn't want to link this .obj file I use the COFF2OMF import library conversion tool.
C:\>coff2omf phile.obj crap.obj

Then I atttempt to use the exported function _printhello in a C program:

#include <stdio.h>

void printhello();

int main() {
printhello();
return 0;
}

I compile it and link it together with phile.obj .
Upon execution an invalid page fault exception occurs and it crashes...
Also, when I try to debug it with ollydbg it gives some warning that it might be a self-modifying file or something.

Can anybody help me?
