I expect it to be incremental.  There's a POC implementation that 
uses the built-in preprocessor that already exists in gdc 
(libcpp), initially none of the C-specific target macros would be 
exposed though - this is one arcane part of gcc/g++ that needs 
rewriting because at the moment using it just opens a [pandora's 
box](https://github.com/gcc-mirror/gcc/blob/31d18ff44244d1fe3ae913a5a1957d82059cb328/gcc/fortran/cpp.cc#L189-L200) (even in other front-end languages).
