I was only talking about procedures functinos which do nothing at all, not
those that aren't fully functional (unless it's not obvious they aren't
fully functional). OTOH, for you it may be OK that sound() doesn't take
the frequency into account under Win32, but we get regular bugreports
about that. Then again, maing it call runerror wouldn't pchange very much
about that probably :)

I'm not sure, but I think it's possible for a program to determine whether
these are supported for a certain mode, so it could adapt itself at

I see your point.

A lot if people will also start looking for a problem if their sound
doesn't work correct, so I don't think that's a valid argument.
