Hello Christian,

  first of all c would be enough. Preprocessing has nothing to do with c++.
Also a lot of compilers allow to use the pre-process stand alone. And then
there is this one little disadvantage. A c compiler doesn't know that it
is not supposed to deal with stuff outside <?php...?> and last but not
least loading a c compiler is not always possible...since it would allow
to use it, which is potentially dangerous. And at last it takes forever
having to load a c compiler everytime you want a php script preprocessed.

best regards
