I don't believe that '$' is required to scan as anything.  Since
it is not in the C source character set, a conforming compiler is
under no obligation to do anything in particular with it and so
is at liberty to do anyting at all with it.  If an implementation
chooses to allow it in identifiers, that's fine (although it
should diagnose the syntax violation - perhaps by congratulating
you for seeing the value of using names containing dollar
signs).
