  I have a much simpler suggestion: If you don't want to modify an identifier
given as parameter, don't assign anything to it. It's that simple.

  If you need a copy of the identifier, then copy it:

#macro foobar(A)
{
  #local LocalCopyOfA = A;
  ...
}

  No need to make the SDL parser any more complicated than it already is.
