Understand. So, it should be dynamic loaded, compiler should know which D 
library to load for used function and this function's name mangling, also 
then phobos should be dynamic library to call it's functions in macro. This 
is non trivial stuff, and compiler itselt is written in C++ so this plugin 
architecture should be working in C++ too. Also when cross-compile it's 
neeaded compiler for both X and Y architectures or two compilers, 
communicating among them. So that compiler for Y when finds macro should 
call compiler X and dynamically load to itself produced function. OK, IMO 
it's too complex and experimental to be of any priority in nearest future.
