Using ccache solves the (tiny) problem as the backend hardly 
every changes.
But even without ccache `make -C src -f posix.mak 
../generated/linux/release/64/backend.a -j8` runs in about a 
second on my machine, hardly anything that needs optimization 
given that it's a solid codebase with little ongoing development.
Also translating the C++ backend to D zero benefit to D users (at 
worst it introduces codegen bugs). I'm inclined to say we should 
rather spent our time on the various more important issues.
It was a good move for the frontend as that will allow us to make 
use of D features to improve the code/architecture and to 
eventually turn it into a proper library.
Converting the stable and well tested codebase of the backend, 
which will hardly receive any feature development, is unlikely to 
ever pay off.
