   As John says, M4 works fine under Windows. You can also install any of   
   the several versions of gcc for Windows (see the FAQ) and use the -E   
   option.  It's not terribly hard to build a simple preprocessor with a   
   scripting language like Perl.  I have looked at mcpp in the past (see   
   Source Forge).  It looks pretty good and works on Windows.
