The parser would probably do something a little more intellegent if the 
standard include files were not included directly but by wrappers, e.g. 
rename colors.inc to something else and create a new colors.inc with the 
following code:

#ifndef(Colors_Inc_Temp)
    	#declare Colors_Inc_Temp = version;
    	#version 3.5;
   	#include "realColors.inc"
    	#version Colors_Inc_Temp;
#else

I doubt it's worth the effort to do this, however...
