Hello!

I'm trying to use the MS WINAPI function sndPlaySound
(http://msdn.microsoft.com/library/sdkdoc/multimed/mmfunc_4uzo.htm) from
within BETA.
The program looks as follows:

---- cut here ----

ORIGIN '~beta/guienv/v1.6/guienvall';

INCLUDE '~beta/guienv/v1.6/private/winnt/guienv_ntiprivate'
		'~beta/guienv/v1.6/private/winnt/stddialogs_ntibody'
		'~beta/win32lib/v1.6/ntinterface'
		'~beta/win32lib/v1.6/winuserconsts';

BUILD nti '$$/snd.obj' 'snd.c' 'betacc $0 $1';

-- program: descriptor --

guienv
(#

SND_ASYNC:(# exit 0x0001 #);

PlaySound: external
     (#
 		pszSound:[1]@char;	(* LPCSTR *)
		fdwSound:@integer;	(* DWORD *)
		result:@integer;
 		enter (pszSound,fdwsound)
     		do 'sndPlaySound' -> callStd;
	 	exit result
#);


  do
  ('gleitab.wav',SND_ASYNC)->PlaySound;


#)

---- /cut here ----

I'm using snd.c just for including the necessary mmsystem.h:

---- cut here ----

#include <windows.h>
#include <stdio.h>
#include <mmsystem.h>
#include <windowsx.h>
#include <stdlib.h>

---- /cut here ----

When I try to compile this program I get the following error message:

d:\beta\tricos\nti\ms\snd.obj : warning LNK4042: object specified more
than once
; extras ignored
snd.obj : error LNK2001: unresolved external symbol _sndPlaySound
snd.exe : fatal error LNK1120: 1 unresolved externals
A Link Error Occurred

Any quick help is appreciated!!
