This is why its N compilers.

Every link in that chain of compilers has to be maintained.

Its not just a matter of maintaining the frontend, but also the glue 
code per version of the backend you target.

Plus druntime and phobos for good measure.

Oh and GCC has rules around what compilers may be used to compile GCC 
for distribution. So if D isn't already on a given target... have fun 
with that.



On the other hand our frontend is already marked up with 
``extern(C++)``, and has manually maintained C++ headers for it.

If only we could take advantage of that.
