When I try to compile my VC++ program (am Using VS6.0). I get the
following error in a header file ATLCONV.H.

c:\program files\microsoft visual studio\vc98\atl\include\atlconv.h(52)

Error executing cl.exe.

and it points to

inline LPWSTR WINAPI AtlA2WHelper(LPWSTR lpw, LPCSTR lpa, int nChars,
UINT acp)
{
    ATLASSERT(lpa != NULL); //points to this line. Error is here
    ATLASSERT(lpw != NULL);

//rest of the header code
}

This is the only error I have. I tried to include assert.h but the
error multiplies... so I had revert back. Since it is showing an error
on the header file, is it BUG in the compiler or something? or am I
seeing things differently?

My Main program has the following include statements

#include "asapdefs.h"

#include "atlconv.h"

#include "stdafx.h"

#include <string>

//#undef new

#import "..\..\SomeTLBfile.tlb" raw_interfaces_only

//someother code

Any inputs or thoughts????
