Sorry for creating this confusion.
I got the warning in a complex recursive tree specification, built with 
macros, and tried to replicate it in a spec as simple as possible.
In the example spec the line 

#version 3.1

occurred, causing a warning which I mistook for the mentioned one.
The 'real' warning was produced by a line like:

   #local seven = plus(3,4)

in which indeed a semicolon is missing.
The warning however refers to the line in which the macro is defined, 
which makes it hard (in large specs) to find the error (as I
demonstrated ;-)  )

Try this for a change:

   #macro plus(X,Y)
     (X+Y)
   #end
   sphere { <0,0,0>, 1 pigment { color <1,1,1> } }
   #local seven = plus(3,4)
