I'm sure translation from D into C were discussed before, not even once,
as a means of diversifying the list of supported platforms.  The culprit
was exception handling.  The conversion to C++ were discussed too IIRC,
but not as enthusiastically for some reason.  I cannot think of any real
blockers for such a `preprocessor'.  Maybe forward references, but the
current D compiler has problems with them as well.
