It would be best to not call SUBST at all, but instead create the drive
substitution yourself.

Under NT/2K/XP, you can use DefineDosDevice(), which does the same thing
SUBST does:

    DefineDosDevice()
    http://msdn.microsoft.com/library/en-us/fileio/base/definedosdevice.asp

Under Win9x/Me, DefineDosDevice() is not available, so you have to instead
use DeviceIoControl() with the VMM32 device driver to indirectly call
Interrupt 21h Function 71AAh:

    DeviceIoControl
    http://msdn.microsoft.com/library/en-us/devio/base/deviceiocontrol.asp

    Calling DeviceIoControl on Windows Me/98/95

http://msdn.microsoft.com/library/en-us/devio/base/calling_deviceiocontrol_on_windows_95_98_me.asp

    Interrupt 21h Function 71AAh Minor Code 0h
    http://msdn.microsoft.com/library/en-us/win9x/95func_8pk8.asp

    Interrupt 21h Function 71AAh Minor Code 1h
    http://msdn.microsoft.com/library/en-us/win9x/95func_8pm0.asp

    Interrupt 21h Function 71AAh Minor Code 2h
