I managed to hack around it. This works for dialog apps anyway.

In each dialog that has ON_HELPINFO, include the following header. In the main program file, comment out this line in the message map: ON_COMMAND(ID_HELP, CWinApp::OnHelp)

helpinfo.h:

#if !defined (HELPINFO_H_INCLUDED__73F6F4A6_FF9C_4ACB_89BF_D72035E02917_)
#define HELPINFO_H_INCLUDED__73F6F4A6_FF9C_4ACB_89BF_D72035E02917_
#if _MSC_VER > 1000
#pragma once
#endif
//==============================================================================

#define AfxSig_bHELPINFO 42

#define ON_WM_HELPINFO() /
    { WM_HELP, 0, 0, 0, AfxSig_bHELPINFO, /
        (AFX_PMSG)(AFX_PMSGW)(BOOL (AFX_MSG_CALL CWnd::*)(HELPINFO*))&OnHelpInfo },
typedef struct tagHELPINFO
{
}  HELPINFO;
typedef void* LPHELPINFO;

//==============================================================================
#endif // HELPINFO_H_INCLUDED__73F6F4A6_FF9C_4ACB_89BF_D72035E02917_
